=== Extensible syntax ===
This simply means that the source language(s) to be compiled must not be closed, fixed or static. It must be possible to add new keywords, concepts and structures to the source language(s). Languages which allow the addition of constructs with user defined syntax are [[Camlp4]], [[OpenC++]], [[Seed7]] and [[Felix]]<ref name="Zingaro2007">Zingaro, Daniel, "Modern Extensible Languages", SQRL Report 47 McMaster University (October 2007), page 16.</ref>. While it is acceptable for some fundamental and intrinsic language features to be immutable, the system must not rely solely on those language features.
