Buffers in cdef function argument list

[robertwb]

The parser doesn't allow

cdef void foo(np.ndarray[X):
    pass

This is because the parser has to support

cdef void foo(int[](float]) X)

and at the point of parsing the [ it isn't known whether is is a definition or declaration (right?)

One could for instance parse to the end of the line and check for a ":" when encountering the [ in a cdef (and store info to coordinate this in the parsing context) -- as the two cases can be seperated on whether it is a definition or not.

Another option is to use a "TrailingBracketTypeNode" rather than let the parser resolve it.

Replying to dagss:

This is because the parser has to support

cdef void foo(int[X)

Here it should have been

cdef void foo(int[](]))

And it seems we can just look ahead a single word to fix it for now...
