Well, since the proposal is four orthogonal ideas, may I vote multiple times? Here goes...

Nice template :-)

-1 on new x{map,filter,...} builtins -- feels like too much at once

FWIW, mxTools provides an xmap() implementation and I've never used it once... so:

-0 for the core +0 as extension

+0.5 on indexed() as a builtin

+1, though I'd prefer an iterator here (over a generator).

+1 on generator comprehensions; I favour the brackets -0 on generater parameter passing, -1 on the particular syntax chosen -0 on generater exception passing, -1 on using "throw"

-0 on those; generators don't work for me as concept... too much magic under the hood.
