Yes! very good idea!
I also added something like static assert(staticIndexOf!(T, Children) !=
-1); to get a compile time error when someone wants to get something
which is not there.
thanks

Hi Philippe,
wonderful solution. I also added
T get(T)() {
return components[staticIndexOf!(T, Children)];
}
to the class to get the Children out by type (works as long as there is only
one child of each type in the tuple).
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)
:)
