My 2nd patch was wrong as I noticed too late yesterady, sorry for that.
Unfortunately I didn't have time to fix it. Here is one that works (at leas= t

using literal elisp. It is not only about being able to omit ';' in comment= s.

The idea is that normally in elisp, compiler skips comment-lines and

org-mode as a kind of annotation tool or organisational tool for the

messages if it was feeded with org headings and so n.

Another possibility is to maybe be able use elisp as a template or

example one could write a C code and use elisp macros or code

Completely agree on that one.

Unfortunately the time and effort and my struggle to just patch
bytecompiler.el to do this tells me I am not the= right person to jump on
implementing "the skip" approach you s= uggest. Maybe some code, or
at least approach used in bytecompiler and eval = can be even reused for
this, but to me personally it would take too muc= h time and effort.

The other approach of copying file to temp buffe= r and modifying the file
is certainly less jobb and easier to implement. = I also agree that it is suitable
for small toys and demo examples. It couldn't be= difficult to implement, one
would need to keep track of balanced paranthesis= + some few other small
things which isn't very difficult. While I can c= ertainly hack elisp to a degree,
I am still not the right person to implement som= ething you would distribute in
Emacs anyway, so if somebod else is interesting = to implement this approach
it would be great.
