Also a good place to talk about https://github.com/ropensci-review-tools/autotest as a way to control you check your inputs correctly?

Oh yeah that's an excellent topic! Incidentally yesterday I was looking at the mlr dev docs and they mentioned checkmate.

Looks like rlang::abort() is having quite an update in the next version. Not sure when this is likely to land but currently it no longer hides the call by default. This has knock on effects with assertions in vctrs as they no longer hide the call by default in an RStudio session

library(vctrs)
f <- function(x) vec_assert(x, integer())
f(1)
#> Error in `vec_assert()`: `x` must be a vector with type <integer>.
#> Instead, it has type <double>.

Anyone have an idea of where they are in their release timeline so the post does not go out of date too quick? 😅
Edit - previous error would have been

#> Error: `x` must be a vector with type <integer>.
#> Instead, it has type <double>.
