Line 797: Several modules in the Comprehensive Perl Archive Network ([[CPAN]]) expand on the basic mechanism: * {{Perl2\|Error}} provides a set of exception classes and allows use of the try/throw/catch/finally syntax. * {{Perl2\|TryCatch}} ~~and~~, {{Perl2\|Try::Tiny}} ~~both~~and {{Perl2\|Nice::Try}} all allow the use of try/catch/finally syntax instead of boilerplate to handle exceptions correctly. * {{Perl2\|Exception::Class}} is a base class and class-maker for derived exception classes. It provides a full structured [[stack trace]] in {{Perl2\|$@->trace}} and {{Perl2\|$@->trace->as_string}}. * {{Perl2\|Fatal}} overloads previously defined functions that return true/false e.g., {{Perl2\|open}}, {{Perl2\|close}}, {{Perl2\|read}}, {{Perl2\|write}}, etc. This allows built-in functions and others to be used as if they threw exceptions.
