Re: Reader flags to indicate different kinds of files Marc Nieper-Wißkirchen 27 May 2020 09:21 UTC

I'd say keep separate things separate. Reader flags should affect how
things are read by `read' procedure (and the Scheme reader) and should
not be (mis)used for anything else. A reader flag for different Scheme
dialects is fine as long as it switches the reader into the
appropriate mode, but the flag itself should not communicate any
meaning of the underlying Scheme data.

This is up to the Scheme data itself. For example, R7RS library
definitions start with a define-library form, R6RS library definitions
with a library form, top-level programs with an import form, etc.
