<div dir="ltr">Another thing I'm a bit confused about is whether or not a #lang-based language is considered to be module-based, as well. I always assumed they were, since #lang is essentially sugar syntax for a module form, but the Adding Languages section of the docs had two separate sections for these, causing me to doubt that assumption. If they are different, would the <span style="font-family:'courier new',monospace;font-size:13px">drracket:language:</span><span style="font-family:'courier new',monospace;font-size:13px">simple-module-based-language%</span> approach work with #lang-based languages? It shouldn't be an issue for me, since my goal is to move away from the #lang syntax here, but it would still be nice to know in the future.</div>

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>
