    // }
    // 
    // Make sure we don't fold two calls to System.currentTimeMillis into one.
    final ParameterExpression x_ = Expressions.parameter(long.class, "x");
    final ParameterExpression y_ = Expressions.parameter(long.class, "y");
    final Method mT = Linq4j.getMethod("java.lang.System", "currentTimeMillis");
