This is a completely different problem again.  There appear to be three
different but interacting issues:

- this one, which could be hairy as we emerge from parsing a $(...)
expansion with an alias unpopped --- I'm not sure yet if that's
tractable without making the code yet more unreadable

- the fact that parse_subscript() made invalid assumptions about what
was going underneath it, now fixed, at least to the point where it's
no worse than it ever was

- where alias expansion takes place, which would presumably be sensible
to define properly but which I haven't yet worked up an interest in.
