Not it's not. Here `typ' is a System.Type instance, and thus, can't be
used as a generic argument for the GenericMethod.

But to me, it seems that here, the whole JIT/gmcs modification is a
little bit too much. Especially as you can use something like a linq
expression tree to create a dynamic method that will call the generic
method with the dynamically retrieved type.

You won't lose too much of performances because of the DynamicMethod
used to compile the expression tree.
