I have a large library of Perl routines that are used in a large system. The code has been written over past several years by several programmers. Lately, we've been writing new code using exceptions, using Error and Exception::Class.

Surprisingly, following the latest OO conventions has led to serious problems and this question of mine. The problem I encountered was that people would change behavior of a function to throw an error, but sometimes forget to place the call in try{} block (mainly because they were not aware the function is called somewhere else). The result is the process mysteriously dying.

Is there a way to force calling functions to place calls to things that can throw exceptions in try{} block? (And I know the answer is probably "no"). Java has this type of enforcement built into the compiler. If there's no programmatic way of enforcing the practice, I'd like to hear how to cope with this besides preaching diligence to every member of the team -- people can still make mistakes.

Thanks for your suggestions!
