This all reads a bit like advertising copy for the ISE commercial product. Is there someone out there who actually knows Eiffel, but also knows something else and can give a more realistic appraisal. (Yes, it does look like a nice language, but there are other nice languages, and this stuff is just over the top.)

== Pure OOArchives ==

I have taken out a lot of preachiness in the recent changes to the "facism" section and tried to make it more factual; however, it was so absurd to begin with (and I am such an Eiffel advocate) that it may require more work.

[[/Archive 1]]

== External links modified ==

Also, I removed unsubstantiated and inflamatory claims that Eiffel compilers are somehow "smarter" than C++ compilers. The discussion of moving runtime analysis to compile time presumably refers to the SmartEiffel compiler's ability to devirtualize method calls, and even to inline dynamically dispatched methods. However, this alone (while clever) is no great compiler breakthrough---Self and Smalltalk have had devirtualization for years---and it certainly doesn't allow SmartEiffel to claim that it's "smarter" than C++ compilers (some of which, in fact, can also do some devirtualization). On the contrary, SmartEiffel produces C code, and therefore leaves all the difficult aspects of compilation to the C++ compiler (eg. optimization, register assignment, etc.).

Hello fellow Wikipedians,

----

I have just modified one external link on [[Eiffel (programming language)]]. Please take a moment to review [https://en.wikipedia.org/w/index.php?diff=prev&oldid=801214014 my edit]. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit [[User:Cyberpower678/FaQs#InternetArchiveBot|this simple FaQ]] for additional information. I made the following changes:

== Silly section ==

*Added archive https://web.archive.org/web/20040604193933/http://cetus-links.org/oo_eiffel.html to http://www.cetus-links.org/oo_eiffel.html

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

For what it's worth, I think the section ''Elegance, simplicity, or fascism?'' is really silly. There are a variety of languages that are simple and more high-level than C, and these comments could apply to any one of them. Moreover, "clever coding tricks" are not what I'd call optimization hints to the compiler; they are hand-optimizations. Finally, "Eiffel seeks to produce a quality software system over anything else" seems to imply that other languages are not designed for this purpose, which is silly — even C was not designed primarily for performance. ''Fascism'' is pretty over-the-top too — I dare anyone to design a "fascist" language. I'm seriously considering deleting this whole section, if there are no objections.

:I agree. The section is a sales pitch. Eiffel leans more toward clarity (over efficiency for example) than many other languages, but this section as it stands doesn't explain that very well. There are probably a couple of nuggets in that section that could be reworked into the article a different way, but on the whole I think the article would be improved by this section's deletion. --[[User:P3d0|P3d0]] 14:38, Nov 16, 2004 (UTC)

:Really, this article needs a serious cleanup. The trouble is, I have found that computer science articles don't stay cleaned up for long. Well-meaning CS people come along and add in their opinions, seemingly unaware that they are not objective facts. That's why I have turned my attention more towards science and astronomy articles lately. :-) --[[User:P3d0|P3d0]] 14:40, Nov 16, 2004 (UTC)

== Renaming mechanism flaw ==

Dear editors:

== Pure OO ==

In 2022, it was discovered that the Eiffel's renaming mechanism has

In the section where it is claimed that Eiffel is pure OO, it introduces control structures that are not in any way object oriented. I'm not a purist or formalist, but if you claim a language to be pure OO, "special form" control structures like loops and ifs should be replaced by message sends (like in Smalltalk). This page really is a sales ad!

serious semantic flaws, please refer to the following repo and pdf doc

for the report, and code example to demonstrate the semantic issue:

Please verify the new findings as reported there, and update the

wikipedia page of the Eiffel language.

BTW, you can also check the following repo for a new design pattern

that solved the diamond problem of multiple inheritance cleanly and
