I looked at the design. It is very solid and elegant, but I suggest we

Part of the point of the path manipulation routines in dmdz.d was to
get around
the fact that dmd/windows doesn't have posix path manipulation.
Another part was
to convert from one to the other. I don't think such scenarios are
tenuous at
all. As far as abstractions are concerned, though, no idea.
I see. But since zip files work on both Windows and Unix, there must be
a common ground of functionality that works for both.
That's because any program/library that manipulates raw zip files on
Windows must also have some POSIX path manipulation capabilities. Right
now, that's in Phobos, but it's hidden from the user.
I'm hoping to
insist on that instead of enacting a schism. After the schism, widening
the incompatibilities will become the path of least resistance.
Are you envisioning a system that auto-detects whether something is a
Windows or a POSIX path and converts it to some OS-agnostic internal
representation? E.g. something like
// Auto-detect Windows path
auto path = Path("c:\\foo\\bar.baz");
I don't think that will work, because the above is a perfectly valid
POSIX path as well, except it's the name of a single file. Just try typing
touch 'c:\foo\bar.baz'
at a Linux command prompt.
The only other option I can see is to have std.path automatically work
with Windows paths on Windows and POSIX paths on POSIX -- which is
exactly what I'm suggesting.
Anyway, I'm not married to this idea, I just think it's a good one. ;)
I still think something needs to be done to std.path, though (and I'm
still volunteering to do it). Did any of my other suggestions seem
worthwhile, or are people happy with the module the way it is? Are
there other suggestions?
