table vs hash-table

[roland.kaufmann@space.at]

				Hello,
FWIW, RScheme (0.7.2, from the RScheme user reference 0.4) uses
'table'.  Actually, it provides an abstract class <table>, but the
only subclasses implemented are subclasses (for certain key types) of
<hash-table>.

Constructor:
  (make-table test-fn hash-fn) => table

Read access:
  (table-lookup table key) => value(1)

  (1) #f if key is not present in the table.

  (table-key-present? table key) => boolean

  #t if key is present, #f otherwise.

Write access:
  (table-insert! table key value) => prev-value

  (table-remove! table key) => value

others:
  (table-size table) => integer

  Number of entries.

(key-sequence table)   => list
(value-sequence table) => list

  Lists of keys and values, in unspecified, but compatible order.

  (table-for-each table proc)

  Where proc takes 3 arguments: hash-code, key and value

HTH,
Roland
