-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
while browsing both guide[1] and reference[2] for a `hash-empty?' procedure I turned up with empty hands, although a few possibilities for implementing it did come to mind, like using `hash-count' and comparing to zero or, using `hash-iterate-first' which returns #f for empty hashes but otherwise returns an integer which is an index to the first element in the hash table (which sounds like hash tables are implemented using arrays and an index to the underlying array is returned). Marijn PS Note how hash table is spelled differently in below URLs [1]:http://docs.racket-lang.org/guide/hash-tables.html [2]:http://docs.racket-lang.org/reference/hashtables.html -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk3jTYgACgkQp/VmCx0OL2xlrQCeNACTfhRe3wcbeOVb2X4oGzqN /OIAn1fGOd/igVsZ2iXCjAKbt+c/xMPT =EIpC -----END PGP SIGNATURE----- _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
