-// This test is checking our logic for structural match checking by enumerating
-// the different kinds of const expressions. This test is collecting cases where
-// we have accepted the const expression as a pattern in the past but we want
-// to begin warning the user that a future version of Rust may start rejecting
-// such const expressions.
-
-// The specific corner cases we are exploring here are instances where the
-// const-evaluator computes a value that *does* meet the conditions for
-// structural-match, but the const expression itself has abstractions (like
-// calls to const functions) that may fit better with a type-based analysis
-// rather than a commitment to a specific value.
