lambda keyword is better than nothing, it definitely can be improved. Just imaging using javascript syntax in your example.

I think with the introduction of list comprehension Guido saw map function was no longer needed, that was why he wanted it removed. I don't deny it, but using map and filter sometimes are just easier to read. Say [foo(v) for v in a] vs map(foo, a).
