OMG.
actions = [
(my_re1, do_something_with_temp1),
(my_re2, do_something_with_temp2),
(my_re3, do_something_with_temp3),
(my_re4, do_something_with_temp4),
]
for my_re, do_something_with in actions:
temp = my_re.match(exp):
if temp:
do_something_with(temp)
break
Having full-blown anonymous functions or Ruby/Smalltalk-like code blocks
would be much more interesting IMHO.
