I think a better way of doing that would be using a runtime-config module as in: http://docs.racket-lang.org/guide/module-runtime-config.html Or I think you can also do that with a #%configure-runtime sudmodule (or something like that)? > On Aug 15, 2015, at 5:08 PM, Matthew Butterick <m...@mbtype.com> wrote: > >> Probably the wiser option.
