 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).
