I amend my statement to "immediately make D as uncompetitive as Zig is"

Note that Zig has a very different idea of integers than D does. It has 
arbitrary bit width integers, up to 65535. This seems odd, as what are you going 
to do with a 6 bit integer? There aren't machine instructions to support it. 
It'd be better off with a ranged integer, say:

    i : int 0..64
