in thread Style & subroutine organization

The way listed here is the canonical way of calling three completely-independent functions in a row. It is very readable and maintainable.

Maintainable, just to go off on a slight rant, is where there are no hidden assumptions. If you were to do:

sub foo1 { foo2(); } sub foo2 { foo3(); } sub foo3{ }
I would assume that foo1() depends on the result of foo2() in some fashion. If it doesn't, then I am very confused. Your piece of hidden information here is that there is no dependence between the function, other than they all need to be executed at the beginning of your script.

If you reduce the amount of information that someone needs to know that cannot be directly deduced from reading the logical structure of your code (you do indent logically, right?), that improves the maintainability of your code. Maintainable code should be your holy grail, above and beyond any other consideration (except for correctness). It should be more important than optimization (save for when business needs demand it).
