Using exact numerical studies of a few particles, the quantum melting of the Wigner crystal is revisited in two dimensions. The existence of an intermediate supersolid phase is suggested between the Fermi liquid and the Wigner crystal. The difference between lattice and continuum descriptions is clarified.
