String::Tagged implements an object class, instances of which store a
(mutable) string buffer that supports tags. A tag is a name/value pair that
applies to some extent of the underlying string.
.
The types of tag names ought to be strings, or at least values that are
well-behaved as strings, as the names will often be used as the keys in
hashes or applied to the eq operator.
.
The types of tag values are not restricted - any scalar will do. This could
be a simple integer or string, ARRAY or HASH reference, or even a CODE
reference containing an event handler of some kind.
.
Tags may be arbitrarily overlapped. Any given offset within the string has in
effect, a set of uniquely named tags. Tags of different names are
independent. For tags of the same name, only the latest, shortest tag takes
effect.
