DMD 2.064.2

string s = "d8011e49-7b28-4506-8ceb-3a5bcda875d3";
auto id = parseUUID(s);
assert(s == "d8011e49-7b28-4506-8ceb-3a5bcda875d3"); // Error

After parse the string has zero length.

Yeah, it consumes the input range. It should be documented that it does so.

Maybe just remove ref keyword from definition?

Parse functions are generally meant to consume the range, this makes them
useful for input ranges (or e.g. streams I would think..)

This is working as designed (similar to the std.conv.parse functions) although
the documentation does not mention this.

For a non-consuming parser for exact strings, use the constructor of UUID.
