I believe I've found a compiler performance bug (or regression, I 
don't have any other compiler versions to test on right now). The 
following programming takes an abnormally long times to compile 
on 2.068.1 and 2.068.2:

import std.range;
import std.array;
import std.conv;
import std.algorithm;
import std.string;
import std.stdio;

enum Instructions: ushort
{
	add = 123,
	sub = 124,
}

uint[ushort.max] inst;

void initInst()
{
         //Removing this line drastically reduces compile time
	alias InstElem = ElementType!(typeof(inst));
}

void main()
{
}
