  The recently proposed rSCAN functional [J. Chem. Phys. 150, 161101 (2019)] is
a regularized form of the SCAN functional [Phys. Rev. Lett. 115, 036402 (2015)]
that improves SCAN's numerical performance at the expense of breaking
constraints known from the exact exchange-correlation functional. We construct
a new meta-generalized gradient approximation by restoring exact constraint
adherence to rSCAN. The resulting functional maintains rSCAN's numerical
performance while restoring the transferable accuracy of SCAN.
