sub main {}, main();

| I've been reviewing the scripts my old boss wrote (for grabbing device
configs, checking router stats etc.) They are always in the format
which includes "sub main { (code) }" and ends with "main ();". What is
the reason for using this format rather than the more basic format
taught in most basic perl lessons/books?
Thanks.

My guess? The author of that code comes from a C/C++ background, and
can't quite grok the concept of executing code not contained in a
subroutine.
