Extremely useful post!

I wanted to use match.arg() for my functions but I was disappointed to find out that the function uses partial matching unlike rlang::arg_match()

# match.arg will not trigger an error

match.arg(arg = "p", choices = c("R", "python"))

# rlang::arg_match0 will trigger an error

rlang::arg_match0(arg = "p", choices = c("R", "python"))
