What does "noparse" mean? It's got to begin parsing before it can
recognize a precommand modifier. Even splitting into words at whitespace
is parsing, of a sort.
Do backslashes still work? What about quotes of various flavors? Care
to predict every possible question of this kind that I might ask?
If there isn't _some_ syntax, you're just using "cat" as your shell; the
input can't be processed in any useful way.
If you want to be able to define your own arbitrary syntax, you need a
language-definition language (like a YACC grammar). How hard would it
be to implement that?
