My bad, I guess once one spends too much time on a problem, it
gets hard to explain. What if I put it this way ?
TypedParameter!(ulong, int, string) p1 = new
TypedParameter!(ulong, int, string)();
Parameter p2 = new TypedParameter!(ulong, int, string)();
writeln(typeid(p2.value.AllowedTypes)); // ()
My dream would be a way to make that last statement return the
same thing as the penultimate one.. If that even is possible.

I can get the correct TypeInfo through virtual functions by
adding a method like this to Parameter and its sub-classes:
override TypeInfo_Tuple allowedTypes()
But as far as I know, I can't use this for instantiating
templates, can I ? Especially since `this` doesn't exist at
