IMO "is_*" functions aren't exactly "convenience" functions, even if
they're only a couple of lines impleme

This is true for every function in a Turing Complete language. Perhaps
we should start using iota or jot? :-)

I would have had no idea how to implement this without extra Googling and

Having the abstraction makes it easier for others.

As does Python already in many cases. For example, os.lstat() doesn't
traverse a mount point (junction). On Wind

+1 on a function is_junction.
I am neutral on the questio
+1 on adding Path.is_junction() that returns False on non-Windows systems.
(I'm a Windows user and I use junctions as well.)

I'm not technical enough here to try to argue which it is closer to. We can
say it's like so and so in implementation, but I just liken it a certain
way.
I think for regular users it makes most sense to just have a specific
function rather than expecting folks to know concept similarities... a

Junctions are mount points that are similar to Unix bind mounts where

I tend to prefer adding isjunction instead of changing ismount since I tend
to not think about junctions as being mounts (but closer to symlinks).. but
I guess either way the closeness of the concepts is a different story than

I'd prefer for ismount() to be modified to always return true for a
junction. This would be a significant rewrite of the current
implementation, which is only true for a junction t
So would you be for specific methods to check if a given path is a junction?

Junctions (i.e. IO_REPARSE_TAG_MOUNT_POINT) are implemented to behave
as mount points for local volumes, so there are a couple of important
differences.
In a remote path, a junction gets resolved o
