On this subject, I have seen code where the developer used prototyped subs to mimic try/catch exception handling: 
try {
   open(TEST, ">$file");
};
catch {
   push(@errors, "Failed to open $file");
   return undef;
};

This basically eval()s the try block, and the catch checks the value of $@. Is this good style? I would think that the eval() overhead would be prohibitive, that is why I have avoided using it.
