How To Install liblexical-failure-perl on Debian 10
Introduction
In this tutorial we learn how to install liblexical-failure-perl
on Debian 10.
What is liblexical-failure-perl
liblexical-failure-perl is:
Lexical::Failure sets up two new keywords: fail and ON_FAILURE, with which you can quickly create modules whose failure signaling is lexcially scoped, under the control of client code.
Normally, modules specify some fixed mechanism for error handling and require client code to adapt to that policy. One module may signal errors by returning undef, or perhaps some special “error object”. Another may die or croak on failure. A third may set a flag variable. A fourth may require the client code to set up a callback, which is executed on failure.
If you are using all four modules, your own code now has to check for failure in four different ways, depending on where the failing component originated. If you would rather that all components throw exceptions, or all return undef, you will probably have to write wrappers around 3/4 of them, to convert from their “native” failure mechanism to your preferred one.
