In an ideal world, it might. However, there is much more overhead associated
with creating and calling a subroutine then using a simple scalar. When you
create a subroutine, Perl needs to create a new namespace, stack, etc., and
then when called, there is quite a bit of code that needs to be executed in
order to pass all of the information (even if there isn't any explicitly
passed) to the subroutine. Although your suggestion would work, I think it's
a bit of overkill for the sake of saying that it's "better programming
practice".
