[racket-dev] submodules

What about specially treating the #:main keyword when it appears in a
module top-level. Everything that follows it gets wrapped in a
(module* main #f), perhaps with #:niam as an end delimiter. Or maybe
#:submodule <id>, if it appears at the top-level of a module could
mean that. Or maybe all new syntax:

#submodule <id> {
.... submodule body for <id> goes here ...
}
