No, but there are some benefits to doing so. For instance, if you
don't use parenthesis with calls to functions perl hasn't seen yet the
parser can become confused:
#!/usr/bin/perl
use strict;
use warnings;
local $\ = "\n";
print add_one 0; #perl thinks add_one is a file handle
print add_one(1); #perl thinks add_one is a function
sub add_one { shift() + 1 }
print add_one 2; #perl thinks add_one is a function
