Make a better interface for informing users of syntax errors inline #15

right now the caret turns red. That might be sufficient, but it's probably not a strong enough indicator.

remember: we don't want the user to get overwhelmed because they keep making syntax errors while they're typing. We want to assist them, not shout errors at them loudly.
