same as Pat.of_string etc. This makes programming and composition easier (avoids calls to Rresult.R.open_error_msg).

It also makes compiler error messages less clear. I haven't used bos in a while. What's the general strategy ?

hannesm commented 2 years ago

Since we can always open the error message (e.g. with Rresult.open_err_msg`), there's no need for this PR.
