Immutable list reverse function

[Martin Sjögren]

Is there a "good" way to write a fast reverse function for immutable
lists?

I tried this:

def reverse(list):
    l = len(list)
    return [ list[l-i-1] for i in range(l) ]

It works, but it's obviously not backwards compatible.
Any suggestions?

What I want to do is basically this:

>>> foo(reverse(create_a_list()))

Instead of having to:

>>> list = create_a_list()
>>> list.reverse()
>>> foo(list)

Hints appreciated

Martin
