I think yet another environment variable can do. PERL_5_10_ISH for example. Detailed warnings will be wanted by developers, so they could set this variable while they are debugging, and leave it off in production. The main advantage of this approach is that it will not be necessary to modify the code to get the detailed warnings.Thread Previous | Thread Next
