By design, the hardware that manages floating point numbers makes a NaN not
equal to everything else, including other NaNs:

Hello,
why does this assertion fail:

there is the std.math.isNaN function which works correctly, but why can
I not just use the comparison ?
Thanks, Joshua

Sure ? dlang.org says they are not:
