Hi,

I don't know whether it is worth an RFC (what is RFC?)

At least, regarding the understanding, when you want to overload +=, it is
not for the source method, but for the regexp itself.  "re.source" returns
a new string, which is independent of the re.  Because a string accepts
the "+" operator, "re.source += str" returns another new string, but the
original re does not change.  The correct way for your intention (when 
it is overloaded) is to write "re += '|abc'".  By the same token, you just
want a regexp to be able to accept the "+" operator (which is actually a
method).

Regards,

Bill
