[Haskell-cafe] Bound and free variables

[Jan Stolarek]

Hi *,

I have a simple question about terminology regarding bound and free variables. Assume I have:

let f x  = let g y = ...
            in g c
in ...

Now:
  - `c` is free in `g` and `f`
  - `y` is bound in `g`
  - `x` is free in `g`. 
  - `x` is bound in `f`

What about `y` in `f`? Is it also bound in `f`? If so then it certainly is bound in a different 
way that `x`. Is there a terminology that allows to distinguish these different forms of bound 
variables?
