How then might one define a block? All lines at the same indent level
and the lines nested within those lines?
i = 5
for my i in xrange(4):
if i: # skips first when i is 0
my i = 100
if i:
print i # of course 100
break
print i # i is between 0 & 3 here
print i # i is 5 here
Doesn't leave a particularly bad taste in one's mouth, I guess (except
for the intended abuse).
