Very nice. I have made a more idiomatic version (in D global
constants don't need to be IN_UPPERCASE), I have added few
missing immutable annotations, and given the benchmark also
counts line numbers, I have made the code a little more compact
(particularly the struct definitions, but I have moves the then
branch of some if on a new line, increasing the line count to
make the code a little more readable, so it's not a unnaturally
compact D code):

Bye,

Regarding what is idiomatic D, isn't `immutable x = rnd.next %
levelSize;` pedantic.
Why not just go with `const x = rnd.next % levelSize;`
Any time the type is a fundamental type with no aliasing there is
no sharing so the differentiation of immutable vs const is
unnecessary. Might as well go with const. immutable says I or
no-one else will change the value. But since no-one else can
change the value it seems overkill, no?
Thanks
