In many other languages, main is "special". The unnamed programmers were attempting to make a facsimile of that "specialness".

Perhaps:

#!perl
use strict;
use warnings;
main();
exit 99; # or other reasonable default exit value

might be better.

Yes, and the attempt at the idiom is a reasonable idea, I have in fact used it for service/daemon style scripts in the past, but `exit 0; # undef works too` is the only "correct" exit code. Everything else is an error state. Since returning false is suggestive of an error in Perl I am reticent to put that lipstick on this pig... or this pig stick on those lips... And that's the way the news goes!	[reply] [d/l]
