In looking at merging fused types, it's time to nail down the syntax. The current implementation is
ctypedef cython.fused_type(list, dict, object) fused_t
This requires an addition to the grammer to allow the "call" syntax in a type declaration, as well as special casing to make it allowed only in a typedef. What about
cython.fused_type[list, dict, object].
One advantage is that indexing is already valid in type declarations, and its the typical syntax for parameterized types. Thoughts? Any other ideas?
I like it, so I'll give another +1. Changing wouldn't be too much work anyways.

P.S. Anyone remember buffers and C++ templated types are dissallowed as typedefs?
Yes, there's even a test for it: tests/errors/buffertypedef_T117.pyx (http://trac.cython.org/cython_trac/ticket/117). But it looks more like an easy fix than a feature.
I could see how for buffers it would require at bit more work, but for C++ types that shouldn't be a problem. In particular, I'm looking at https://github.com/cython/cython/blob/master/Cython/Compiler/Parsing.py#L261... - Robert
