Perl::Critic::Policy::CodeLayout::ProhibitParensWithBuiltins
Conway suggests that all built-in functions should be called without parenthesis around the argument list. This reduces visual clutter and disambiguates built-in functions from user functions. Exceptions are made for my, local, and our which require parenthesis when called with multiple arguments. return is also exempt because technically it is a named unary operator, not a function.
my
local
our
return
open($handle, '>', $filename); #not ok open $handle, '>', $filename; #ok split(/$pattern/, @list); #not ok split /$pattern/, @list; #ok
