What can this possibly mean? What semantic interpretation would lead you
to the conclusion that you should stop reading the token after a `$(' in
this one specific case?
by flat non lexical text parsing, excepts for quotes but then $( logically
expands, excepts:
but imho the topic here is how far to expand shell stuff at this position,
however factically its just needs to be a constant data separator
Well, you'd certainly have something here if your shell did that. It
wouldn't be a POSIX shell, though.
