For purely stylistic reasons I'd use subroutines rather than functions for
2 reasons:
1) Its removes the possible confusion that copy is a variable. This is
easily checked, but slows down code comprehension by others.
2) It makes documentation generation using keyword spotting much easier.
Its trivial for HTML converters to spot CALL(
but much harder to spot the difference between functions and variables.
