Actually, he's COMPARING the two, not assigning.  But comparing a
function object and a tuple is still not going to do anything sensible.

This is good advice.  I was assuming that the question was about regex
and would be grown into a more complex pattern match in the final
application.  If all you really want to do is see if a constant text
string like "Domain:" is in a string, regex will work but is overkill.
