eval, backquote, compilation

[Julian Bradfield]

I realized that I don't really understand how byte compilation works.

In particular:

I have a function that involves matching against a long multi-case
regexp, which is most easily constructed rather than spelt out, but
which is constant.

So what I'm doing currently is:

(eval `(defun myfn (args)
        ...
        ,( code to construct regexp )
        ...
))

I have no idea how this interacts with byte-compilation.
Does it "just work"? Or do I end up with a byte-compiled file that
will have the main code of myfn uncompiled?

If it doesn't "just work", what should I be doing?

Thanks,
Julian.
