Yes, exactly.  Actually Guido also mentionned pointy brackets:

If I look at a very recent blog entry of Guido, it seems the idea is 
still in the air:

I wrote the PEP to see if was the only one that would benefit from 
generic types *before* having optional static typing in the language.

It seems I'm the only one;)

According to blog entry 86641, Guido himself is prototyping with 
__getitem__.  However, I cannot do the same, because the framework I use 
is much more complete and keyword arguments are a must.
