Re: Why does using aset sometimes output raw bytes?

I think it's less severe (`aset` can end up changing (by side-effect)
a unibyte string to multibyte, i.e. changing the nature of the object,
which I believe is the only time we do something like that), but yes
similar problems appear elsewhere (hence the "mostly" above).
