With real generics you don't need casting hack.

We have MI in Python and it works somewhat. And I'm sure SI isn't needed
anyway. There must be some design patter mapping SI in assembler or even on
a turing machine.

They aren't out yet and people are already complaining that they are too
limited. So far, despite an horrible syntax and horrible error messages the
C++ templates are still much more powerful than C# generics. And the best
thing is that the constraint system you can find on for C++
templates is more powerful than the one you have in Eiffel either :D
