Only one or two years ago, I remember reading Python constructs that would be removed from Python -- reduce was one of them -- and other constructs that would be emphasized like comprehensions and generators. I saw a very nice description of how Python could be made more functional here, and I was wondering on which list lambda appeared, supported or soon-not-to-be supported.

lambda is not deprecated, and will continue to be part of the language. Attempts have been made to find an alternative, but nothing fruitful ever came from that.

Quoting a post by Guido van Rossum in 2006:

After so many attempts to come up with an alternative for lambda, perhaps we should admit defeat. I've not had the time to follow the most recent rounds, but I propose that we keep lambda, so as to stop wasting everybody's talent and time on an impossible quest.

reduce() was moved to the functools module, so out of the built-in namespace, because its use in Python has always remained obscure. map() is still there though, as it was shown to be very useful still.
