Hi Stefan,
Just to clarify: the ? we propose in the NEP is really for matmul - it
indicates a true missing dimension (i.e., the array cannot have outer
broadcast dimensions as well). For inner loop broadcasting, I'm proposing a
"|1" post-fix, which means a dimension could also be missing, but can

Hi Stefan,
That looks quite nice and expressive. In the context of a discussion we
have been having about describing `matmul/@` and possibly broadcastable
dimensions, I think from your description it sounds like one would describe
`@` with multiple functions (the multiple dispatch we have been (ar

Interesting. If nothing else, it would be a nice way to mark our internal
functions, including the loops. It also should not be difficult to have
(g)ufunc signatures exported in that way, combining `signature` and `types`.
In more detail, I see the grammar clearly allows fixed dimensions in a way

Hi Travis,
More of a detailed question, but as we are currently thinking about
extending the signature of gufuncs (i.e., things like `(m,n),(n,p)->(m,p)`
for matrix multiplication), and as you must have thought about this for
libgufunc, could you point me to how one would document the signature in
