[racket] Macro Stepper with custom languages

What does this expression return, where you replace #lang racket with
#lang spenlang (or pop-pl I suppose):

> ((read-language (open-input-string "#lang racket"))
   'drracket:opt-out-toolbar-buttons
   '())

If it raises an error, that would explain what's going on.
