Hmm. What should it do then? Raise an exception? h1.update(h2) will
overwrite corresponding keys in h1, so there is a precedent for collect_into
working in that way.

I would rule out, say, automatically promoting a value into an array. It's
too application-specific. If your application does in fact hold a hash of
arrays, then I think you'd code your append method accordingly; in other
cases, the structure may be different (a hash of hashes, say), in which case
the append method is different.

Cheers,

Brian.
