That would make the core dependent on the re module,
which I think would be a bad idea.

Personally I like the way the compilation step is
made at least somewhat explicit. Regular expressions
are not strings; a string is just one way of representing
a regular expression. There could potentially be other
representations that compile to the same re object.
