(I'm adding Jürgen to the Cc: list. I have evidence that this may not be
related to gnu-apl-mode, but rather to gnu-apl itself.)
It appears that reshape is somehow mutating certain empty objects to
which is applied.

The above is from my gnu-apl-mode session. Interestingly, I *do* see the
bug when reshaping zilde, but *not* when reshaping the empty character.
Here's the interesting bit: I *can* reproduce the reshape zilde bug
without gnu-apl-mode. The transcript in GNU APL by itself (started in a
Bash shell as `$ apl`) is identical to the transcript shown above.
Furthermore, here's evidence to suggest that the bug may only be tickled
by a reshape of a constant value. (This is a transcript of a
gnu-apl-mode session after having restarted APL to clear the mutated
zilde.)
