  auto a = A!8();

a._data is filled with garbage instead of zeros because the
no-argument constructor is called instead of the one that I've
defined.

structs are always default-constructible, and, as a tie-breaker, a 
function definition that has the exact number of arguments is considered 
a better match one that has to supply default-arguments to match. You 
could use a static opCall to make auto a = A!8() work.
