It's your call, of course.  But being trained as a mathematician, I
pay attention to what the specific meanings of words are.  And the
Bash manual page uses "expand" and "evaluate" in the ways I've
described in almost all places.  If you don't care to keep the
meanings of the two words distinct, feel free.
