I noticed in random.d, uniform template, that popFront is called in different
locations for integral compared to floating point types: for integral types you
.front first and .popFront afterwards, but for floating point types you start
with .popFront and then check .front.

This has a peculiar effect: for example, if you do uniform(0.0,100.0) followed
by uniform(0,100) there's a big chance that the integral part of the first
random number is equal to the second random number.

import std.stdio, std.random;
void main()
{
 writeln(uniform(0.0,100.0));
 writeln(uniform(0,100));
}

The location of .popFront should be standardized, either before or after any
.front.
