R devel - May 2021 - `mode`

Hello,
Kindly revise the documentation for `mode` to reflect
foo <- function () {}
typeof(foo)
# [1] "closure"
mode(foo)# [1] "function"


`help(mode)` states:
Modes have the same set of names as types (see typeof) except that

??? types "integer" and "double" are returned as
"numeric".

??? types "special" and "builtin" are returned as
"function".

??? type "symbol" is called mode "name".

??? type "language" is returned as "(" or "call".

I am presently reading `help(mode)` on:

write.dcf(R.Version())
# platform: x86_64-w64-mingw32
# arch: x86_64
# os: mingw32

Indeed, that help file is missing  "closure", ...
amazingly, for all the history of R (of 25+ years).

Thank you!

I've already fixed this in the sources' trunk (svn rev 80321) a
minute ago; of course this will not make it anymore into R 4.1.0
but in its "patched" version, and then 4.1.1 and one.

With thankful regards,
Martin
