This scares me enough to always put parens around function calls
You know what's really scary? Depending on how you place your
parens, that might not save you
. Say you want to call a method (does the new rule count for subroutine calls as well?) which takes an argument, and add 1 to the result. Just like in Perl5, you use parens:
obj.method ($arg) + 1;
In that case, you might as well have not put the parens there - it's equivalent to:
obj.method ($arg + 1);
If you want to be save, and not depend on unnatural (unnatural in the sense that all major programming languages I know don't have their expressions change meaning depending whether there's a space before an opening paren or not) whitespace rules you have to use an extra set of parens:
(obj.method ($arg)) + 1;
