Absolutely definitely yes!
I would love this functionality. would make the file much clearer and
reduce the need for me to hand check peoples submit files when they
are wrong.

I would suggest using a syntax of the form "use strict" or equivalent
in the submit file and once that is encountered you are forced to use
the correct syntax. Eventually you could phase this in as the default
behaviour and finally (if you no longer feel the benefit of supporting
the old code parse path obsolete it).

All for making this easier to read.

Slight issue with how you deal with some one doing something like

set foo = X

where foo is (or becomes) a keyword for the submit settings (not that
it wouldn't behave badly at the moment but you could handle it more
pleasantly in the new scheme)...
