$@​ is not set in this code despite the fatal error in the eval.

#!/usr/bin/perl -w

use strict;
my $foo = eval "sub { doh }; print qq|hello world\n|";
die "oopsy​: $@​" if $@​;

The output for me is​:

Bareword "doh" not allowed while "strict subs" in use at (eval 1) line 1.
Unquoted string "doh" may clash with future reserved word at (eval 1) line 1.

This bug is mended in the development releases.

In 5.005_03, the errors are generated as warnings, so as a workround,
you can set a $SIG{__WARN__} to convert the warnings into die(), or
otherwise flag the error.
