Name collision is one reason.

If two different piece of the script ask for different subs but with the
same name, one or the other will prevail and the other will get the
wrong code. If you `use warnings;` and name the subs with the same
name, the compiler will complain about the name collision.
$ perl -Mwarnings -e'sub foo{} sub foo{}'
Subroutine foo redefined at -e line 1.
