  Decays of the type $B\to D hh^\prime$, where a $b$~hadron decays to a neutral
charm meson that can be an admixture of $D^0$ and $\overline{D}{}^0$ states
together with two light particles that are typically a kaon and a pion, have
demonstrated potential to enable precise determinations of the angle $\gamma$
of the CKM Unitarity Triangle. The current status and future prospects of these
measurements are reviewed.
