message: Ignore a clippy lint that we don't care about
  Summary: We care about the panic message, so don't want to use assert! directly
diff: //! Run conformance tests, which are used by the Go starlark.
  //! e.g. <https://github.com/google/skylark/tree/master/testdata>
  +
  +// `if_then_panic` is only in newer clippy, delete this in future.
  +#![allow(unknown_lints)]
  +// We want to carefully control the panic message.
