---------------------------------------

[~jorisvandenbossche] do you think it's worthwhile keeping an issue open for this?

> UUID objects can be easily supported and can be represented as 128-bit integers or a stream of bytes.
> The fastest way I know to construct a UUID object is by using it's 128-bit (16 bytes) integer representation.
>  
> {code:java}
> %timeit uuid.UUID(int=24197857161011715162171839636988778104)
> 611 ns ± 6.27 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> %timeit uuid.UUID(bytes=b'\x124Vx\x124Vx\x124Vx\x124Vx')
> 1.17 µs ± 7.5 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> %timeit uuid.UUID('12345678-1234-5678-1234-567812345678')
> 1.47 µs ± 6.08 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
> {code}

> Right now I have to do this manually which is pretty tedious.
