Re: eval-when, eval-when-compile

KMH> Byte compile the following two programs and look at the output. (setq blah1 (eval-when-compile (require 'regexp-opt) (regexp-opt '("blah" "oink" "blah2" "blah3")))) (setq blah2 (eval-when (compile eval) (require 'regexp-opt) (regexp-opt '("blah" "oink" "blah2" "blah3")))) KMH> Why don't they produce the same thing? Actually, read the Lisp standard. Here is Chapter and Verse: http://www.xanalys.com/software_tools/reference/HyperSpec/Body/speope_eva... (eval-when (compile)) is supposed to do NOTHING at compile time, unless it's a top-level form. This is a Common Lisp thing, not an XEmacs invention. I didn't try to understand why. Martin
