Prop lists vs. dictionaries

Certainly not for efficiency. Proplists are handy for passing
options to a function, using defaults, overriding, combining, etc.

If you pass a proplist to control the behaviour of some heavy
computation, I recommend that you internally pick out the values
from the proplist and put them in a record or dictionary for
quick access before you enter the main loop.
