front-end/interaction in drscheme:language:module-based-language->language-mixin

This method is just like front-end/complete-program except that it is called with program fragments, for example the expressions entered in the interactions window. It is also used in other contexts by tools to expand single expressions.

• (send a-drscheme:language:module-based-language->language-mixin front-end/interaction port settings teachpack-cache (-> (union sexp syntax eof))
     port : input-port
     settings : settings
     teachpack-cache : drscheme:teachpack:teachpack-cache

  Reads a syntax object, from input. Does not use settings.

  For languages that use these mixins, there is no difference between this method and front-end/complete-program.
