If _rebinding_ is what we're after, then why not go all the way an
introduce a rebind operator? Say ':='. Augmented assignment would also
become rebinding then (hm, I hear the sound of code breaking in the
distance ;-) Add that to MWH's function/class filter patch and you can
write:
count = 0
def _thunk(line) [iterclose(open('blah.txt'))]:
if line.find('Python') >=0:
count += 1 # or count := count + 1
print line,
Not nice that _thunk needs to be named, but perhaps the function name
can become optional:
count = 0
def (line) [iterclose(open('blah.txt'))]:
if line.find('Python') >=0:
count += 1
print line,
How's that for a change of direction? ;-)
I'm just throwing in an idea, I'm not saying I like this (I don't know
yet).
