[plt-dev] Whither DrRacket Tools

I think that you want drscheme/private/rep.ss's submit-predicate to
reflect the current language. All of the stuff that is #lang-line
specific is connected in via the module-language (ie the class
implementing drscheme:module-langauge:module-language<%> interface)
and there's no path that connects that class to the rep's submit
predicate for now. I guess one would add something to
drscheme:language:language<%> and then provide a default
implementation in one of the functions that produces those things.
This is, unfortunately, likely to be a backwards incompatible change
tho. So maybe there is some other way things should be organized going
forwards. Like perhaps the repl should start doing things like (is-a?
... drscheme:module-language:module-language<%>)  to give special
abilities to the module language.

Or maybe just wait until I find time. :(
