The problem in python here is that it needs to always recompile the
regexp. I would like to have a way to write a regexp as a constant and
then python should compile that regexp to the byte-code file.

This is a problem when one has a big amount of regexps. One example is
the xmlproc parser in PyXML,

This is not a problem in a program that continues to run long times,
but I want short lived programs like command line apps.

Of course we do have ways to go around that limitation, but that is
just ugly.
