Implementing the random algorithms/other wrappers as a class is

hap.random, and came to the conclusion that it wasn't a valid 
approach.

 What about an alternative allocator? Specifically I'm thinking 
in C's equivalent which is alloca (allocates directly on the 
stack with the rest of the variables). If the constructor is a 
function then that won't work; but if it's inlined then it should 
work.

 I suppose the alternate is an option to skip/throw away some 
numbers that should've been consumed (assuming you want to keep 
using the same seed), or seeding each per use.
