-// This test of structural match checking enumerates the different kinds of
-// const definitions, collecting cases where the const pattern is rejected.
-//
-// Note: Even if a non-structural-match type is part of an expression in a
-// const's definition, that does not necessarily disqualify the const from being
-// a match pattern: in principle, we just need the types involved in the final
-// value to be structurally matchable.
