in thread Test::Exception extension with (evil?) overloading

Ohhhh! Much better. With a tiny piece of magic we can get rid of that shift too.

sub lives_and (&$) { my ($test, $name) = @_; local $Test::Builder::Level = $Test::Builder::Level+1; { my $ok = \&Test::Builder::ok; no warnings; local *Test::Builder::ok = sub { $_[2] = $name unless defined $_[2]; $ok->(@_); }; use warnings; eval { $test->() } and return 1; }; if ($@) { fail($name); diag("Died: $@"); }; return; }

Which allows us to do:

lives_and { is 42, 42 } 'answer is 42'; lives_and { is 24, 42 } 'answer is 42'; lives_and { is sub { die 'oops' }->(), 42 } 'answer is 42';

giving us

ok 1 - answer is 42 + not ok 2 - answer is 42 + # Failed test (foo.pl at line 29) + # got: '24' + # expected: '42' + not ok 3 - answer is 42 + # Failed test (foo.pl at line 31) + # Died: oops at foo.pl line 31.
