You can also "override"1 a builtin with the &foo() syntax. You can also pass your current @_ through with it, if you leave off the parens. 

sub time {
     print "Is on my side\n";
     print &bar, "\n";
}

sub bar {
     my ($baz) = @_;
     uc $baz;
}

&time('yes it is'); # prints 'Is on my side', a newline, followed by '
+YES IT IS'

1 OK, maybe it's not truly overriding, because of the special syntax you have to use to call it. 

perl -e 'print "How sweet does a rose smell? "; chomp ($n = <STDIN>); 
+$rose = "smells sweet to degree $n"; *other_name = *rose; print "$oth
+er_name\n"'
