Comment (by mcandre):

 Either of two behaviors would be great:

 * Just the expression evaluates, prints, and the user is returned to the
 terminal shell prompt.
 * The expression becomes the first thing run and printed in a normal ghci
 session.

 I don't mind which of these happens, as long as ghc does one of them.
