Current challenges and future prospects for $\gamma$ from $B\to D hh^\prime$ decays

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.
