sorry, forgot the error message:
--------
Error: function std.uuid.UUID.opEquals (ref
const(UUID) s) const is not callable using argument types (UUID)
Error:
UUID([cast(ubyte)138u,cast(ubyte)179u,cast(ubyte)6u,cast(ubyte)14u,cast(ubyte)44u,cast(ubyte)186u,cast(ubyte)79u,cast(ubyte)35u,cast(ubyte)183u,cast(ubyte)76u,cast(ubyte)181u,cast(ubyte)45u,cast(ubyte)179u,cast(ubyte)189u,cast(ubyte)251u,cast(ubyte)70u])
is not an lvalue
