Indeed, that's easier for the user this way.
In that case, you might want to either return a tuple of one or more
type (when there is more than one of a given type) or put a
restriction on Components so it's only a set of types.

Maybe with:

... if(NoDuplicates!(Children).length == Children.length)

See http://dlang.org/phobos/std_typetuple.html#.NoDuplicates


Then, when you're feeling masochistic, the next step is to allow
assignments from other Components with a permutation of children,
because Component!(int,double) is not much different from
Components!(double, int)
