Inject code as node, not source strings?

[henrik]

Hi! I've played with Prism + require-hooks for metaprogramming, inspired by strict_ivars.

I've followed a pattern of using Prism to find source locations, then modifying the source code string around those locations.

But this feels fragile. For example, in one experiment, escaping got a bit messy to avoid injections.

Does Prism offer ways of modifying code via nodes? E.g. "insert an X node after this other node I found", or "change the value of this integer node from 1 to 2" or similar? Or is that considered outside its scope? Didn't spot anything in the docs.

My brain switched into second gear and found a nicer way of getting this escaping right, but the question still stands :)
