map/filter/reduce/lambda opinions and background unscientific mini-survey

None of them are really indispensible. Map and filter cab be replaced
with list comprehensions. reduce is redundant except when multiplying a
series; there's a sum function for a reason. Lambda looks cleaner in
some cases, but you don't gain any functionality.

What really struck me, though, is the last line of the abstract:

"I expect tons of disagreement in the feedback, all from
ex-Lisp-or-Scheme
folks. :-)"

Guido wrote somewhere that the original map, filter, and reduce came
from a lisp hacker who missed them.
