If I understand the question correctly it is about handling the case where an
argument is left out
that is supposed to be aliased in cases like, e.g.:
1. USE ARG >someArg
2. USE ARG >someArg=123
If so I would assume/expect in case 1. that "someArg" has not assigned a value.
It would be as if
the ">" operator only gets applied to an argument if an argument was supplied.
In case 2 I would assume/expect that its value would be "123".
In both cases aliasing to another variable would not take place, if the
argument was left out.
