>>> u = toCF('Data:').CFURLCreateWithFileSystemPath(kCFURLHFSPathStyle, False)
>>> u.CFURLCopyFileSystemPath(kCFURLPOSIXPathStyle).toPython()
u'/Volumes/Data'
>>> u = toCF('Foo:').CFURLCreateWithFileSystemPath(kCFURLHFSPathStyle, False)
>>> u.CFURLCopyFileSystemPath(kCFURLPOSIXPathStyle).toPython()
u'/Foo'

Yeah, I see what you mean.  You can't expect this kind of conversion
to work on a nonexistent file, and it's not one-to-one in any
case... I'd suggest just documenting it and leaving it.
