I think that may be possible already using current-load-port.
Something like

        (define-module (foo bar)
          ...)
        (my-zany-reader)

where `my-zany-reader' reads and parses from current-load-port and
does whatever with the results, like make new defines presumably.

This could be used for the entire rest of the file, or stop at some
point like a "here-document" perhaps.

Wouldn't be compiler-friendly, but I wouldn't worry about that until
there's an actual compiler to be friendly with :-).

`load' is pretty simple, isn't it?  One can make a new open/read/eval
without too much trouble.  I guess there's bits like path searching
and current module saving.  Maybe they only need to be better
documented though.
