Hi all, I really like the addition of `R_NewEnv()` back in 4.1.0 https://github.com/wch/r-source/blob/625ab8d45f86f65561e53627e1f0c220bdc5f752/src/main/envir.c#L3619-L3630
I have a use case where I'm likely to call this function a large number of times to generate many small hashed environments, so I'd like to optimize it as far as possible. I noticed that it takes `int size`, converts that to a SEXP for `R_NewHashedEnv()`, which then simply converts that back to an `int` here: https://github.com/wch/r-source/blob/625ab8d45f86f65561e53627e1f0c220bdc5f752/src/main/envir.c#L378 I wonder if we could cut out that intermediate SEXP (along with its protection) by adjusting `R_NewHashedEnv()` to instead take `int size`. I'd be happy to do a patch if that sounds good. I'd update all uses of `R_NewHashedEnv()` to supply `int`s instead, which actually seems like it would make every instance of calling that function simpler: https://github.com/search?q=repo%3Awch%2Fr-source%20R_NewHashedEnv&type=code So hopefully a win everywhere?
