drracket:language:module-language<%> : interface?
The only language that implements this interface is DrRacket’s “Use the language declared in the source” language.

(send a-drracket:language:module-language get-users-language-name)
 → string
Returns the name of the language that is declared in the source, as a string.

(drracket:module-language:add-module-language) → any
Adds the module language to DrRacket. This is called during DrRacket’s startup.
(drracket:module-language:module-language-put-file-mixin super%)
 → (implementation?/c text:basic<%>)
  super% : (implementation?/c text:basic<%>)
Extends super% by overriding the put-file method to use a default name from the buffer, if the buffer contains something like (module name ...).
