Printing a Hash

Problem

You want to print a hash (keys and values).

Solution

Using recipe HashRecipeTraverse we can easily print all the elements in the hash:

(let ((t (make-immutable-hash-table '((1 . "one") (2 . "two")))))
  (hash-table-for-each t (lambda (key value)
                           (display (format "~a: ~a~n"  key value)))))
