Yeah, comparing interfaces to each other can get really complicated when you're
dealing with generics, considering you basically have to do the same thing as
the compiler with respect to:

-enforcing constraints
-variance rules
-handling polymorphism

And then of course you have to be able to recurse / handle generics nested
within the generic signature. 

Alas, the framework doesn't provide an easy way to ask if one generic interface
can be substituted for another -- that's left as an exercise for the reader
AFAIK.

I've actually worked recently on a bit of similar code that uses reflection to
find extension methods for a given type.  Haven't finished it for the same
reasons -- it's complicated ;0  It works in the simpler cases, but it falls
down in more complex generic scenarios.

So I totally understand why this won't make it into 2.10.
