Query: From geometric quantization to Moyal quantization   We show how the Moyal product of phase-space functions, and the Weyl
correspondence between symbols and operator kernels, may be obtained directly
using the procedures of geometric quantization, applied to the symplectic
groupoid constructed by ``doubling'' the phase space.
