Sure it will -- if your textbook has

  #lang htdp/beginner

examples, then that will be pretty obvious.

Given that Module will be the only one left eventually, what you're
arguing is against having "#lang scheme" as the default text.  (And
IMO, having no text will be frustrating, and having "#lang scheme" or
"#lang ???" will be much more confusing.)

My vote still stands.
