Try:
short[][kie];
In D structs/classes usually start with an upper case letter:
struct Kie { short a, b; }
But if you want to use Kie as key in an associative array you
have to add it the full hashing protocol of three functions:
equality, hash function and comparison.
A simpler solution is to use a Tuple, that already defines
those three methods:
alias Kie = Tuple!(short,"a", short,"b");

Thanks. Coming to D from python, I have to say D's tuples look
difficult. I'm going to see how far I can get with structs
writing my sudoku solver.
