cwilcox - new version
I?ve been looking at this for a couple hours--it ended up being trickier than I expected to implement well.
I?ve attached a new patch here. This version scales significantly better than the existing method for both `pwilcox` and `dwilcox`. Examples are included below.
I can?t think of any other ways to improve runtime at this point. That?s not to say there aren?t any, though?I?m hopeful

New syntax for positional-only function parameters?
Dear List,
I'm writing to gauge interest in new syntax for positional-only
function parameters to be added to R.
The pattern of functions accepting other functions as inputs and
passing additional ... arguments to them is prevalent throughout
the R ecosystem. Currently, however, all such functions must one
way or another tackle the problem of inadvertently passing arguments
meant to go to

lang3() always constructs a new language object. If you do end up using
eval(), it may make sense to move lang3() out of the loop and reuse the
existing object

I see you have a new Matrix (1.7-0 from 2024-04-26 with a new ABI) but
an older lme4 (1.1-35.1 from 2023-11-05).
I reproduced the crash and the giant backtrace by first installing
latest lme4 and then

Confusing lstat() performance
Hi,
I have a gluster 3.10 volume with a dir with ~1 million small files in
them, say mounted at /mnt/dir with FUSE, and I'm observing something weird:
When I list and stat them all using rsync, then the lstat() calls that
rsync does are incredibly fast (23 microseconds per call on average,
definitely faster than a network roundtrip between my 3-machine bricks
connected via Ethernet).
But
