The snippet I showed you doesn't intercepts wrong values at compile time,
but rather at run time.

Hi All,
I want to pass an integer to a sub. The only
valid values of the integer are 1, 2, 4, 8, and 16.
Other than using "if" to test their values, is
there a way to state that an integer can only
have certain predefined values?
Many thanks,
