Anonymous function syntax

[Jason House]

std.algorithm already introduces a sort of lambda syntax...
map!"a+b"(...) or map!q{a+b}(...)

If D is looking for its own style of short lambda, maybe implicit use of a and b could be extended.
Candidates:
a+b
{a+b}
f{a+b}
auto{a+b}
auto a+b

Personally, I like the 2nd or 3rd one. The second is visually cleaner while the 3rd is easily parsed and feels very similar to q strings. I picked f because that's frequently used to represent a function. x could work, but that's a common variable name...
