Multiple range enumeration

Hi,
If I have multiple ranges, say:
auto a = [1, 2, 3];
auto b = ["a", "b", "c"];
auto c = ["x", "y", "z"];
I'd like a composition range that enumerate all combinations of
these ranges,
having the same effect as a nested foreach loop:
foreach (i; a) {
foreach (j; b) {
foreach (k; c) {
writlen(i, j, k);
}
}
}
Is there such a generic function in std lib?
