Could you try to point out whats wrong with map & filter?
It's hard to do stuff like this:
assert(9.iota.emit!(int,(put,a){if(a%2) put(a*a); if(a%3==0)
put(a);}).equal([1,9,3,25,6,49]));
Is it a bug or you forgot 0 here?
How it looks with Phobos today:
auto r = new Generator!int({
9.iota.each!((a) { if (a % 2) yield(a*a); if (a % 3 == 0)
yield(a); });
});
assert(r.equal([0,1,9,3,25,6,49]));
Probably much less efficient, of course.
