Actually, now that I see this - it actually makes sense to think of a
parametrised type as a meta-type that maps types to types, so a mapping
syntax makes sense here. If you have more than one type parameter, it'd
look like this:
myinst = MyClass[(sometype, someothertype)](*args)
and the concrete type would basically be 'looked up' at compile time.
It doesn't directly map to an 'obvious' declaration syntax, but I guess
cdef MyType(object) [(sometype, someothertype)]:
...
works well enough.
So I'm +1 on this, too.
