Get return type statically

I have a type
public class SuperFunction(T)
{
T t;
return(T) Do() { return t(); }
}
where T is a delegate or function. First, I would like to be able
to specify that this must be the case for SuperFunction so we
can't pass non-function/delegates for T. Second, How to specify
the return type of Do to match that of T.
e.g., SuperFunction!(bool function())
then return(T) should be bool.
Similarly, I would like to extra the T's parameters and make Do
have them also.
This way, SuperFunction!T.Do emulates T in every way.
