My understanding of your explanation is that it shouldn't work.
It shouldn't and probably isn't working. If nothing else, when you use to!(x)(y), "x" should be the type that you're trying to convert into. So I would expect your code to be to!(int[2][2])(a). I would still be impressed if that worked, since std.conv is intended more for parsing strings into ints and stuff, not for splitting and grouping arrays.
Your assertion probably succeeds because in memory a two dimensional array is arranged with the first row followed by the second row. So a flat array of four items and a 2-D array of two arrays of two items end up laying out the same in memory. Some how it's going straight to memory and comparing them that way (maybe).
