Hi Jan,

I should have checked this; it is entirely my fault.
I had presented a possible implementation for it, but it turns out it was wrong, a working implementation that would behave correctly is much more complicated:
Thus, explaining why (static_cast<T>(x) == x) wouldn't work, and why it is annoying enough that warrants being written on someone's behalf.
