/**
 * NOTE: this test originally checked that values of classes inheriting from functions could be invoked as functions.
 * However, Function{n} / ExtensionFunction{n} classes were incompatible with JS functions our lambdas were compiled to.
 * This led to runtime errors (see KT-7692), so the test is temporarily disabled.
 *
 * TODO: support inheritance from function types and re-enable this test
 * NOTE: inheritance from extension function is forbidden now
