Report source location when errors happen

Currently it just throws an error with description, it would be nice if it also provides information from node.position to a user (source if available and line).

i haven't looked into rework's source stuff yet. would take a PR!

[jonathanong]

oh that's so simple. did you just want err.position = position? or did you want err.start = position.start, etc. there should be a de factor standard for this.

yeah it would be nice if we could just try/catch and make err.message a snippet of near the failure, usually it's something obvious that you can see right away

[jonathanong]

the try/catch should go into rework, not the plugins, right? so you're okay with err.position = position?
