Notice that all the procedures must have the same parameter profile. There
are cases where this isn't what you want.
There are also nesting issues (you can't have a top level array linking to
nested subroutines) [Note to language lawyers: The last sentence was not
meant to be a formal definition...]
So in many cases you may decide (after thinking about "access procedure" and
"access function") to use a dispatching routine that is invoked with an
"opcode" (operation code) and calls the appropriate routine.
