Curiously, I also work with "people with less expertise in Perl" and our coding standards similarly mandate always using parens (and no leading &) when calling non built-in subroutines. We had this standard in place long before PBP in response to a specific incident here when an inexperienced Perl programmer simply changed "use" to "require" so as to load his (procedural) module at runtime rather than compile time. Unfortunately, this broke his code that was calling the module's functions without parens, and, due to his inexperience with Perl, he struggled for hours to figure out what was going wrong. If I understand correctly, the OP in this node had a similar problem and similarly spent quite a bit of time figuring it out, time that might have been saved by following this coding standard.
