} This error is definitely what I would expect from the above command.
} It's expanded in the subshell

If this were a normal command alias, I'd agree with you, but this is
a global alias -- the parent shell should expand it wherever it is an
unquoted shell word in the original command line, before the subshell
is ever started.

The "workaround" I posted in 37122 behaves the way you're thinking,
but shouldn't be necessary.

I suppose there's an argument to be made that a word inside $(...) is
"quoted", but if so. the example I showed for "typeset frobozz[$(foo)]"
(where xyz is expanded before parse_subscript() is called) must be
wrong.
