=head1 NAME
Acme::ExceptionEater - Prevents eval from returning an exception.
=head1 VERSION
This document describes Acme::ExceptionEater version 0.0.1
=head1 SYNOPSIS
use Acme::ExceptionEater;
eval {
my $ee = Acme::ExceptionEater->new();
die 'My final wish is for you to know this...';
};
# $@ is still ''
=head1 DESCRIPTION
Placing an Acme::ExceptionEater object in a lexical in the
outer-most scope of an C<eval> will prevent exceptions from
escaping the C<eval> where they may confuse, annoy, frighten,
or inform others.
Simply instanciate an Acme::ExceptionEater object at the
start of the C<eval>. When the eater goes out of scope and
Perl does garbage collection, it will eat any exceptions
that might be waiting to pass on their final words to
the code after the C<eval>.
