Summary: re propagates opaque exceptions

Initial Comment:
If you call re.compile() with an erroneous expression,
the
underlying extension module (pcre, sre, ...?) raises an
exception which is propagated through re to the caller.

In order to catch the exception, it seems that you need
to
use an unqualified except clause, unless you import the
extension module, which is presumably supposed to be
opaque (particularly if its identity is variable!)
