+ A general sequence representation with arbitrary
+ annotations, for use as a base for implementations of
+ various collection types, with examples, as described
+ in section 4 of
+
+ * Ralf Hinze and Ross Paterson,
+ \&quot;Finger trees: a simple general-purpose data structure\&quot;,
+ /Journal of Functional Programming/ 16:2 (2006) pp 197-217.

+
+ For a tuned sequence type, see @Data.Sequence@ in the
+ @containers@ package, which is a specialization of
+ this structure.
