It has been noted recently that CP asymmetries in such singly-Cabibbo-suppressed (SCS) decays can affect the determination of the weak phase $\\gamma$ using the Gronau-London-Wyler method of comparing rates for $B^+ \\to D K^+$ and $B^- \\to D K^-$, where $D$ is a superposition of $D^0$ and $\\od$ decaying to a CP eigenstate.
