Thank you Jonathan,
for your submitted suggestions.
to have a more generally working (and [dim]names preserving) "outer()" has
been (some where low) on my todo list, for a while now.

Something for all R package / code writers :
--------------------------------
When writing *.Rd files {aka man pages}:
Please use at least one \keyword{...} line at the end
(use a keyword from R.../doc/KEYWORDS
... are these in the Windows version?)
These are important for several indices (and may become more important in
the future).
---
A few more remarks of (half) general interest:
- Concerning "kronecker", couldn't we use
%x%
as an .Alias for the kronecker product (instead of "%kr%" which you proposed)
Does anyone see a reason against it?
- match.fun() [your new proposal]:
Why should it give an error [stop()] instead of return NA or NULL or
something like that when there's no function match ?
