No, rakitzis's rc accepts both syntaxes. That's why I didn't submit an
issue for it.

If enough people tell rakitzis that compatibility with Plan 9 rc would
be great, maybe (s)he will change his/her mind? It's just one change!
And then scripts using the common subset would run fine with either shell.

Or someone could fork rakitzis's rc and resolve issue #19 [1].

Or someone could fork Plan 9 rc and add history.
