Actually a --fu variable is not that useful in Plan 9: % --fu=bar % echo $--fu rc: null list in concatenation % echo "$--fu" rc: null list in concatenation % ls /env '/env/*' /env/--fu ...
So rc can create a variable starting with more than one '-', but can't use it. So I wonder if there is a definition of "the right thing" that can fix this incongruence and also allow the UNIX usage.
