I looked at the design. It is very solid and elegant, but I suggest we
save it for a different opportunity. Scenarios in which code running on
a platform yet needs extensive functionality for the other are a tad
tenuous.

Makes sense. On an overall note, without having much time to look into
this, I wish very strongly we strive to define OS-independent path
abstractions before defining OS-dependent ones. Once the Windows vs.
Posix breach is in, it'll only grow larger because it requires less
design to put stuff in there.
I think I may be explaining myself a bit badly here, so please allow me
to clarify:
For the most part, I want std.path to work *just as it does now*.
If you call doStuffWith(path) on POSIX, it does stuff in the POSIX way,
and if you call it on Windows, it does stuff in the Windows way. Code
using it will automatically work on both platforms.
The only difference will be that if you for some reason need to
manipulate non-native paths, you will be allowed to do so by adding a
prefix to your functions, e.g. Path!posix.doStuffWith(path).
Rationale:
* The code is already in Phobos, it's just string manipulation
and doesn't require any special OS support, and there is
thus *no need* to hide it from the user inside version(OS)
blocks.
* Handling non-native paths is not an obscure need. Examples
include:
- FTP and similar
- Archive manipulation (for instance, the ZIP format uses
POSIX paths internally)
I'd argue that this doesn't introduce more of a Windows/POSIX breach
than there already is in Phobos. I mean, in principle there is nothing
preventing you from adding OS-specific stuff to std.stdio except common
sense, and it will be the same here.
