in reply to Style: buried variables or double referencing?

Good programming style: High Cohesion, low coupling. That doesn't only apply across modules, but also applies to functions and code within the same module.

I will use a small sub to return the count so that how you actually implement the count is abstracted from the caller's logic:

for $i (0..varcount($some_variable)) { ... } sub varcount { # you can implement the count any way you like # and change the implementation any time you like, # the caller will not get affected, as long as the # interface to varcount is unchanged }
