I would be slightly worried that this could conflict with
some future syntax for decimal float literals.

Also, there would still be some tricky parsing issues,
since you have to get all the way up to the 2D (or at
least the comma) before you realise what's going on.

Another approach would be to use a different kind of
brackets, such as

   cdef ndarray{int, 2D}
