+### Dictionary
+
+    (import util-dict)
+
+This module implements a simple key/value dictionary using lists as
+backend. All operations are O(n) with respect to time.

+    (make-ldict [equality?/pairs [pairs]])
+
+* ```equality?/pairs``` - procedure or list of pairs
+* ```pairs``` - list of pairs
+
+Creates a new ldict with configurable equality procedure, optionally
+populating it with initial data.
+
+If only one argument is given, the procedure checks whether it is a
+list of equality procedure and acts accordingly.
