scoping problem

[Paul Jarc]

I'm new to Scheme, so maybe this isn't a bug, but this script:
#!/usr/local/bin/guile -s
!#
(let ()
  (define x #t)
  (define y x)
  #t)

gives me this error:
ERROR: Unbound variable: x

I had thought the definition of x was supposed to be visible
throughout the body of the enclosing (let).  I can work around it like
this:
#!/usr/local/bin/guile -s
!#
(let ()
  (define x #t)
  (define y (lambda () x))
  (set! y (y))
  #t)

But if possible, I'd like to do it all in the (define) form, without
using (set!).
