Okay, Page 20, "Computer Science & Perl Programming", edited by Jon Orwant, Chapter 3, article title is Perfect Programming. I'm not making this up: Quote: When it's in effect, you can't use the bareword style of calling subroutines with no arguments (e.g. $result = mysub;) unless the subroutine was declared before its use, either with a prototype or with the subroutine definition itself. EndQuote:

use strict 'subs';

print count;   # an error with use strict 'subs'

sub count;     # prototyping count() is sufficient

print count;   # Not an error because Perl now knows about count()
