> Scheme is the only one o the three that has t.c.e. as a language feature, of course. Though Common Lisp implementations have been providing it for decades. 't.c.e.' is an optimization feature of various Common Lisp compilers. > Scheme is far, far more performant than C.L. and that's due to language design choices. That's not the case. Actually Common Lisp has a lot of language features which make it performant: stack allocation hints, type hints, inline declarations, compilation semantics, implementation specific feature limits, etc. One of the design goals of Common Lisp was to support optimizing compilers on various platforms.
