anonymous-function

I'm aware that you can write anonymous functions in Scala but I'm having trouble trying to convert a piece of code from Scheme.

Could anyone help me convert this to Scala?

(define apply-env
 (lambda (env search-sym)
  (cases environment env
    (empty-env ()
      (eopl:error 'apply-env "No binding for ~s" search-sym))
    (extend-env (var val saved-env)
  (if (eqv? search-sym var)
    val
    (apply-env saved-env search-sym)))
    (extend-env-rec (p-name b-var p-body saved-env)
      (if (eqv? search-sym p-name)
        (proc-val (procedure b-var p-body env))          
        (apply-env saved-env search-sym))))))

Thanks in advance

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More
