R: Diagnostics crash related to passing tree sitter nodes back and forth with R

[DavisVaughan]

library(abind, package = )

Just put that code in an editor, it should crash immediately. I see something like:

Screen.Recording.2024-04-03.at.2.19.36.PM.mov

Likely caused by: Error: RAW() can only be applied to a 'raw', not a 'NULL'

this error is pretty telling, as there is only one real place we use RAW(), and thats when we pass the raw tree sitter node back and forth with R.

I think it is coming from here, where I think node here is NULL

I think the matched call here really does have NULL as the package = arg

We have removed the offending code a while ago.
