...n-API" just to show the possibility of future breaking changes. Whether you call it API or non-API, clever users will still accept the breaking changes on it if it's reasonable. For example, how about "experimental API" or "unstable API"? They sound better to me.

...ustWork = FALSE) == normalizePath('./a/b', mustWork = FALSE) but it became FALSE at some point in r-devel. I think 'a/b' and './a/b` should be treated as the same path. Does that make sense?

Hi Yutani, ALTREP is part of the official R api, as illustrated by the presence of src/include/R_ext/Altrep.h. Everything declared in the header files in that directory is official API AFAIK (and I believe that is more definitive than the manuals). The documentation of ALTREP has lagged behind its implemen...

...n-API" is considered a violation of CRAN repository policy, which means CRAN will kick out the R package. I know many CRAN packages use ALTREP, but just being accepted by CRAN at the moment doesn't mean CRAN will keep accepting it. So, I want to clarify the current status of ALTREP.

...ename of "C:/" should be "C:/". However, at the same time, I don't feel this is worth a breaking change, so I think we can preserve the current (R 4.2.2) behavior.

...;t have even a single mention of ALTREP, the term "ALTREP" itself or any entry points related to ALTREP. Does this mean, despite the widespread use of it on R packages including CRAN ones, ALTREP is not the API and accordingly using it in distributed packages is considered illegal?

...separator,' but I don't see how the root path is supposed to be treated based on this rule (, whether it's WIndows or UNIX-alike). What should we expect as the return value of dirname("C:/")? I feel the current behavior on R 4.2.2 is right, but I'd like to confirm. Best, Yutani [[alternative HTML version deleted]]
