Yes, split() is certainly "brute force".
If you have bench-marked this, you know that this is a very "expensive operation".
@array = split (//,$some_var) is super "expensive" and your code does it many times.

Going "with the flow" of the language is (usually) going to execute faster and in general "be better", meaning easier to understand.
