The parens help Perl disambiguate subroutine call vs. method invocation.

That works perfectly, thank you. But I'm a little unclear on the reason. What's the difference between a subroutine and a method in Perl?	[reply]

I don't know what gaal was thinking, but that's not it. The problem is that `Term::ReadKey::ReadMode` in `Term::ReadKey::ReadMode 2;` is a bareword unless you load Term::ReadKey. With strict enabled, Perl gives a warning instead of trying to disambiguate what you meant. For this reason, a lot of people recommend always using parentheses around all subroutine and method call arguments.	[reply] [d/l] [select]
