I agree with Macrakis that first-class functions are a lot wider topic than anonymous functions. To show that I can simply mention the fact that function may return ordinary OR anonymous function. So in theory - language can support first-class functions by operating only with ordinary functions. This illustrates that in general first-class functions has nothing to do with anonymous functions. However in practice first-class functions are much more useful when used in conjuntion with anonymous functions. So at most - anonymous functions can be only sub-topic of first-class functions. (Albeit we can`t ignore possibility that mentioning anonymous functions here can obfuscate understanding of first-class functions) <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/84.32.222.96|84.32.222.96]] ([[User talk:84.32.222.96|talk]]) 09:04, 22 February 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
