Come on, surely someone knows how to. I've already tried the 
obvious, but it doesn't work.

MersenneTwisterEngine!(ulong, 32, 624, 397, 31, 0x9908b0df, 11, 
7, 0x9d2c5680, 15, 0xefc60000, 18) rndEngine;
rndEngine = MersenneTwisterEngine(seed);

"shift by 32 is outside the range 0..31"
"static assert  (false && 4022730752LU <= 0LU) is false"
"instantiated from here: MersenneTwisterEngine!(ulong, 32, 624, 
397, 31, 2567483615u, 11, 7, 2636928640u, 15, 4022730752u, 18)"
