I thought I had tried and it had failed.  Of course, now you suggest it, it
works ;-).  I had thought that maybe coerce_array kept changing val1, as it was
done for each update, but indeed it looks like the first call finds the
underlying type and further calls do nothing.

I'm in no hurry for this one.  I can re-submit later when I have more
confidence that it's right, if no-one can endorse it for me.
