I would like to be able to define a loop statement
(nevermind why) so that I can write something like
loop 10:
do_something
instead of
for i in range(10):
do_something
Possible? If so, how?
Thanks,
Alan Isaac

It's not possible to create a new statement, with su

Yes. By implementing a compiler or an interpreter for your programming

It seems that you are looking for macros; maybe Logix "languag

No, not in the way you think it is. What you can do instead is
something like this:
def do_something(i):
... do_something ...
def loop(n, func):
for i in range(n): func(i)
loop(10, do_something)

Ruby and Smalltalk are both good at this kind of thi

Whoops. Should be "while loop()".

Maybe:
while Loop(10)():
print "OK"
Looks rather ugly but requires one less line ;-).

Here's a flagrant hack:
import sys
VAR_NAME = '__repeat_counter'
def set_repeat_counter(value):
frame = sys._getframe(2)
frame.
