C translations ?

4 observations

• The kind of things that constructive does is low level
• constructive is a bit slow
• We always fall back to the same functions
• I need to learn a bit of C at some point and this is a great way to get started using llms

I'm afraid to lose a bit of readability but I'd like to give this a try.

• Start with the leaves, with the intermediate objective to have deparse_call() do all the recursive code in C.
• Implement all the stuff called by .ctsr_construct.default() in C
• Implement base R classes in C

In different tickets!
