I love your templates as much as the next guy, but let's not forget the 
possibility of using different function names instead of templating 
everything!?

I couldn't find good names. uniformOpenClosed, uniformOC, 
uniformOpenLeft... what would be some good names?

And, as other have said, I'm ok with [) since that's what rand()%max 
boiled down to as well. Futhermore, since arrays in D are also [), users 
of D get used to it so it's not odd at all.

Ok. Let me just note that rand()%max is a lousy method of generating 
random numbers between 0 and max-1 and everybody should put that in the 
bin with Popular Examples That Should Never Be Used, together with 
exponential Fibonacci, linear-space factorial, and bubblesort.
