No idea myself but that's where it seems to go wrong.
Looks like a bug. Just to make it more visible:
auto clobber(ref Set x, ref Set o) {
writefln("entered clobber - x.aa: %s", x.aa);
Set ret;
writefln("did not touch x.aa - x.aa: %s", x.aa);
ret.aa = x.aa;
return ret;
}
x.aa changes during the second call:
entered clobber - x.aa: [1:true]
did not touch x.aa - x.aa: [1:true]
entered clobber - x.aa: [1:true]
did not touch x.aa - x.aa: [] <-- What happened?
