The Error module provides two interfaces. Firstly "Error" provides a
procedural interface to exception handling. Secondly "Error" is a base class
for errors/exceptions that can either be thrown, for subsequent catch, or can
simply be recorded.
.
Errors in the class "Error" should not be thrown directly, but the user
should throw errors from a sub-class of "Error".
.
Warning: Using the "Error" module is no longer recommended due to the
black-magical nature of its syntactic sugar, which often tends to break. Its
maintainers have stopped actively writing code that uses it, and discourage
people from doing so.
.
Recommended alternatives are Exception::Class (libexception-class-perl),
Error::Exception (not packaged), TryCatch (libtrycatch-perl), and Try::Tiny
(libtry-tiny-perl).
