It seems following is invalid:

I prefer to reduce scope of variable as much as possible, so
I find this restriction unconvinent. Is is part of standard or technical
limitation? Is it any workaround?

The problem is that you have an invalid `let` form. You need an _expression_ besides `define`.

Something like this would be valid:

(let ((a 2))
  (define (foo x) (+ a x))
  (foo 4))
