Fate of lambda, Functional Programming in Python...

In a comment off a post on lambda-the-ultimate, I noticed this little 
offhand remark:

'''IIRC GvR is going to kill the various lambda, map,filter & reduce 
leaving just generator expressions/list comprehension.'''

If this is considered generally true (at least in the 
straight-from-the-rumor-mill sense) I'm hoping someone here can either 
provide the backstory on this or point me in the direction of related 
discussions on python-dev (it's **real** hard to do a search on that 
list's archives when one's main keywords are lambda, map, filter, 
etc...).

I'm quite fond of lambda, and it seems to have plenty of uses aside 
from munging lists in connection with map calls (i.e. passing one-off 
comparators to cmp()).  Of course, my first "real" programming language 
was lisp, so perhaps I'm biased.   (You should see all the anonymous 
classes I throw off in Java!)

Anyway -- back to your regularly scheduled decorator-discussion of the 
day.   ;-)
