The context here involves concurrency where bar() calls yield and

We're not addressing that. += is not supposed to do concurrency
magic. -- Andrei
It's not += doing the magic, it's bar(). And it's not limited to
concurrency, it happens with every side effect:
import std.stdio;
void main()
{
int a = 0;
int bar()
{
a++;
return a;
}
a += bar(); // => a = a + bar()
writeln(a);
}

which one is correct?
