// |jit-test| error: ReferenceError
// We elide the uninitialised lexical check for the second access to |x|,
// because we statically know that the first access will throw an error.
// `!x` is compiled straight from bytecode without going through any ICs, so
// already on first (eager) compilation we may be Warp compiling.
function testNot(x = (x, !x)) {
function inner() {
// Close over |x|.

}
}
