// Regression test for https://github.com/dart-lang/sdk/issues/56412.
//
// The combination of named arguments in any position and finalizables leads
// to nested let expressions. Let expressions introduce scopes. Often variables
// get hoisted into a parent scope which is usually a block. But this specific
// regression test has a variable declaration in a let scope.
// (The bug was that in the compiler, let expressions were not entering scopes.)
