redss has asked for the wisdom of the Perl Monks concerning the following question:

I have a program that calls a method from a package, which sometimes makes the program die (all logic & syntax is correct)

How can I make perl trap the error, so that it will continue instead of dying?

    See the documentation for eval.

    eval block do a good work for what you wants, but I recomend you to look of Exception classes or Error class at CPAN site. IMO theses classes implements good practices of exception management.
