if (isSomeChar!C);

version (Posix) assert(driveName("c:/foo") .empty);

{
assert(driveName(`dir\file`) .empty);
writeln(driveName(`d:file`)); // "d:"
writeln(driveName(`d:\file`)); // "d:"
writeln(driveName("d:")); // "d:"
writeln(driveName(`\\server\share\file`)); // `\\server\share`
writeln(driveName(`\\server\share\`)); // `\\server\share`
