@typescript-eslint documents recommends turning off the base
unused-vars rule in eslint explicitly and using '@typescript-eslint/no-unused var'
instead. In this case, the base rule failed to correctly report enums. (reported
unused even though they were used).
Also, fixed two unused variables by adding ignore pattern '_'.
