FREE is deceiving here – Perl Programming Language Review

You can download the app for free and run the sample code already given for free. That's it! If you even want to test the app for any other code sample then you have to pay. IMHO listing app as paid and pricing it to $2.99 would have been a true description. As $2.99 is the payment you have to make to get unlimited compilations.
