  We show that one can re-arrange the Heavy Quark Expansion for inclusive weak
decays of charmed hadrons in such a way that the resulting expansion is an
expansion in $\Lambda_{\rm QCD} / m_c$ and $\alpha_s (m_c)$ with order-one
coefficients. Unlike in the case of the bottom quark, the leading term includes
not only the contribution of the free-quark decay, but also a tower of terms
related to matrix elements of four quark operators.
