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
Hi everyone,
I'm glad I'm able to contribute back to this discussion thread. I wanted
to post a quick message to this group to make sure there is no
mis-information about XND which has finally reached the point where it can
be experimented with (http://xnd.io) and commented on.
XND came out of t
