Perl exceptions instead of return values

Question

In some perl scripts I find myself writing things like:

open(...) or die $!; print ... or die $!;

etc.

I'd like to avoid repeating myself saying or die ... at the end of every possible exception.

Is there a way to force functions like open() etc to throw an exception when they error, not just a false return value? Then I could catch all possible exceptions in one go.

Yes. It exists a module that makes those instructions die on an error, it's called autodie. Add it at the beginning of your script.

use autodie; ## It dies. open my $fh, '<', 'nonfile.txt';
