Unfortunately I do not see any ambiguity in my original code.
It _is_ confusing (the situation of the same name being used both in the main
function and the sub-function was an accident, not intentional).
But I cannot see what rule of D has been broken.
To me, if nothing else, D's scope rules should have stopped any problems.
