The fix is pretty trivial, bools where not supported for the simple fact that
they are not on the "support" list.

The fix is:

1. std.conv:

Line 1309 Change:
T toImpl(T, S)(S value)
    if (!isImplicitlyConvertible!(S, T) &&
        (isNumeric!S || isSomeChar!S) &&
        (isNumeric!T || isSomeChar!T) && !is(T == enum))

To:
T toImpl(T, S)(S value)
    if (!isImplicitlyConvertible!(S, T) &&
        (isNumeric!S || isSomeChar!S || isBoolean!S) &&
        (isNumeric!T || isSomeChar!T || isBoolean!T) && !is(T == enum))

2. Traits:
Line 5691 Change:
template mostNegative(T)
    if(isNumeric!T || isSomeChar!T)

To:
template mostNegative(T)
    if(isNumeric!T || isSomeChar!T || isBoolean!T)

I don't have time to fix this myself right now, but if someone else does it,
and writes the corresponding unittests, I'd be glad to review it.
