This RFC proposes using @#array, analogous to $#array, to get the list of
upper bounds for a multidimensional array @array. The length of @#array
would indicate the dimensionality of @array.
That's fine. This RFC does not seem to touch on the question what

I disagree. You end up with a situation where some

No, everything would be in a scalar context. If you used tie() to
specially tie a variable, then you might be able to overload +, *, -,
etc, but this is no different

I'd like to suggest that it is not a very good idea to start dividing
the world into PDLers and non-PDLers. There are a multitude of reasons
but I am not keen to go into details.

Maybe we need "denit" for "de-nitialize" :)...
Yuck. I dislike "de-" anything. "un-" is far more
often the correct prefix. Anyway, the counterpart
of "init" should be, I think, "exit". But seriously,

Probably we'll have to say that the user must explicitly zip if that
is what is desired.
PS Yes, please. I view the flattening of lists as a feature, not a bug, and

Would returning the array of status be sufficient?
@foo = chmod 755, "bar", "baz", "quux";
# @foo == (0, 2, 0);
How to convert them to error messages would be a challenge.
Unless passing them through $! would do the trick.
Hmm, perl -wle '$!=3; print $!'
No such process
