This one is definitely caused by Bug 7295, but I'm reporting it as a separate
issue because the effect on Phobos is a regression.  The regression should be
fixed for next release come Hell or high water, even if 7295 is not fixed and
we have to resort to a workaround.

import std.algorithm, std.typecons;

void main() {
    RefCounted!int a, b;
    swap(a, b);
}

std\algorithm.d(1491): Error: pure function 'swap' cannot call impure function
'refCountedPayload'
