test $thing->method should do something {
  ..
}

should simply add a test called 'thing_method_should_do_something' to the test class.

Meanwhile

foreach my $method (qw/subject body/) {
  test "responds to $method" {
    ok $self->{instance}->$method();
  }
}

should generate a couple of tests in the obvious way. Variables should be interpolated in double quoted strings, not otherwise.

use Test::Class::Sugar (
  -default_prefix => 'MyTest::Suite::',
  -test_instance  => '$self',
);

testclass exercises SomeClass {
  test policy changes {
    ok $self->isa('MyTest::Suite::SomeClass');
  }
}

Sometimes assertion comments are enough:

test {
  ok 1, "I prefer to name my tests like this";
}

Right now, when things fail, they fail spectacularly. Okay if you don't fuck up, not so okay otherwise. Make the parser fail gracefully.

No idea how to do this yet...
