I'm trying to upgrade some code to run correctly in Perl 5.14. However, I still need it to work in older version of perl.
I would like to have certain code execute only if Perl 5.14 is detected. Essentially I'm looking for something similar to the #if MACRO #endif construct in C.
My specific use case is that I need use re '/d'; in order for some existing regular expressions to want with 5.14 but earlier Perl versions will give a compile error if I add this pragma.
I've searched extensively but I haven't found any information for how to do something like this. So any suggestions would be greatly appreciated.
Thanks in advance
