Perl strict Benchmark

This is a Example-Benchmark about to turn off things you don’t need in Perl:

use Benchmark qw(:all) ;
cmpthese(-1, {
'dev'      => sub {my($x,$y) = (4,3); $x = $x/$y;},
'strict'   => sub {my($x,$y) = (4,3); use strict; $x = $x/$y;},

Our Result:

            Rate    dev strict 
dev    3841286/s     --    -8%  
strict 4170472/s     9%     --

Maybe a good solution is to use it to check your code and then to comment it out, maybe with a debug variable, for this take a look at Perl Debug Output.

(This is just an Example, don’t turn of use strict.)
