Then you get "interesting values of undef" :).  Seriously, I suspect one
of the following:

1 - runtime error
2 - each row (or column) of @b numified to its length
3 - the first element of each row/col of @b
4 - the other arrays boosted to the highest dimension

I like #2, because it is easy and keeps hyper-operation simple.  If those
aren't just numeric operators, but some other weird user-defined thing,
then an array as one operand makes sense.  The simpler hyping is, the
better, IMHO.  Some people doubtless like #4 because it's a natural
extension of the way scalars get auto-boosted to one-dimensional arrays.
As a middle ground, we could have

5 - use /\^<$n><operator>/ to do a nested $n-dimensional hype

Oh, yeah.


who regrets opening his mouth...
