- express engine support deep opt of example:
assert_eq!(exec_expr(&arg, "(1+1)"), json!(2));
assert_eq!(exec_expr(&arg, "(1+5)>5"), json!(true));
assert_eq!(exec_expr(&arg, "(18*19)<19*19"), json!(true));
assert_eq!(exec_expr(&arg, "2*(1+1)"), json!(4));
assert_eq!(exec_expr(&arg, "2*(1+(1+1)+1)"), json!(8));
assert_eq!(exec_expr(&arg, "(1+2)+(8*(2+1)*9)"), json!(3+8*3*9));
