The docs do tell you that `rng` is an optional parameter of 
`uniform`:
https://dlang.org/phobos/std_random.html#uniform

However, there are often good reasons to want to pass a specific 
RNG: you may want to pick the specific RNG algorithm, and you may 
want to be able to know exactly how it was seeded, e.g. if you 
want to be able to reproduce the same results.  I assume that 
Eric's use case may reflect that.
