Unlike Error.pm, with Error::TryCatch you can return() from anywhere, but see CAVEATS below. All functions named after this in that import list will raise an exception only when they are called in void context i.e.

That can land you in a boatload of trouble. If this scalar reference is set on return from the catch block, then the try block continues as if there was no exception. Have an exceptional time !! On our way, we'll be touching upon the advantages of using exception-handling over traditional error-handling mechanisms, exception handling with eval {}, problems with eval {} and the functionalities available in Fatal.pm.

These values are what will be returned by the overload methods.

The equivalent code with exception handling is shown below.

Any suggestions on how to fix CGI::Session ? This page will help you create a private CPAN library. For example the following code will cause Error.pm to throw objects of the class MyError::Bar by default: sub throw_MyError_Bar { my $args = shift; my $err = MyError::Bar->new(); $err->{'MyBarText'} = $args->{'text'}; For building the CPAN modules from sources it is assumed that you have a fully working Perl and C development environment (including a C compiler and make tool) - but you
