FWIW, my reason for using prototypes in a situation like this:

sub helper ($$$) { ...
sub foo {
   # code that calls helper
[download]

is because it does check the prototypes, since it's not a member dispatch or anything like that.

Specifically, if I add a parameter to the helper (or remove one) as I tinker with the code, the compiler will catch any uses I didn't update.

Basic idea: in situations when they do offer checking, why not give the compiler all the information you can?
