The problem with that format is that any variable I have in the main routine, like $name above, is in scope for the whole file. If I'd misspelled $name in the argument list to say_hello(), it could have given rise to a hard-to-trace bug.

Put your subroutines first, at the top of the file, and the 'main' code at the bottom.
