ast dump

[sbarzowski]

It's going to be useful for development of tools.

For now it's possible to have a generic dump using go-spew (https://github.com/davecgh/go-spew).

It would be very interesting if we can dump ast as go source files, then we can dump ast of stdlib as go source code, and embed it into vm, thus avoid parsing stdlib every time. Any idea?

That sounds good. A bit unrelated to debugging use case here, so I opened a new issue for that (#100). Thank you!
