Well, the problem is that we'd *not* be keeping it the same for
user-defined types. But the odds that that's really an issue are
admittedly small.
I thought of an argument for changing to array-uses-element's-typdelim,
though. If we ever go over to a scheme where arrays are one-dimensional
and you build up N-dimensional arrays using arrays of array objects
(where the outer array treats the inner as a black box), then we would
need the typdelims to match to preserve the current I/O behavior.
I'm not really enamored of making such a change myself, but I seem to
recall a couple of people advocating for it.
So, if no objections I'll revert the change to _box's typdelim and
change DefineType to copy the element typdelim to the array type.
