Could you explain to me why ? When does one want to use
(eval-when-compile ...) ? I know at least one for sure, macro
compilation, but why not for variables or even functions ?
Is the byte-compilation process and/or eval-* functions well
covered somewhere in the emacs documentation ? I read a lot,
googled a lot but nothing really helpful (even the elisp manual
is pretty poor on that).
Thank you,
Xavier
