There was a discussion a while back in trying to get Ruby looking like
Python using an indentation scheme and I posted a possible solution to

There is also the Lazibi library ( sorry no link .. google it ) that
does a similar thing.

I thought to be fair I'd have a hack in the opposite direction and see
if I could emulate Ruby's block notation in Python without
preprocessing. Turns out that you can get pretty close though if a bit
ugly due to the statement vs expression nature of the language.

Note that in python a return statement from within a function with a
yield statement is illegal some some ugly workaround is necessary.

A few short examples .....

from ruby import rubyfi

#Ruby's inject method
def inject(ret, iter, a = 0):
    for x in iter:
       a = yield a, x

#Ruby's collect method
def collect(ret, iter):
    r = []
    for x in iter:
       x = yield x,

# Do a sum over a range
for r, s, x in inject ( range (1,6), 1 ) :
print r()

# Generate a list
for r, s, x in inject ( range (1,6), [] ) :
print r()

# Collect some items
for r, x in collect ( range (1,6) ) :
print r()

The library and some details is at

Can this be developed a little further or a little cleaner?
