It would be nice if a small example was shown (like the examples shown when implementing a reader language). I am also unsure of where this implementation should go in my language directory: should it be in its own file? in the same file as the language module? The documentation suggests that I might be interested in the predefined simple implementation of the interface, </font><font face="courier new, monospace">drracket:language:simple-module-based-language%</font><font face="arial, helvetica, sans-serif">, and I think that is what I am looking for, but again there is the question of where I should be using this in my language implementation.</font></div>

My current approach is to just make each of them a #lang language, but grouped together in a collection, and that's working out fine. But I would like to see if I can do it in a similar way to the HtDP languages, such that the user chooses the language from a group in the Choose Language menu, and doesn't use #lang syntax.</div>
