<P>
A SingletonClosure represents a value that has not yet been evaluated: the value is represented
by an expression, together with saved values of all the context variables that the
expression depends on. The value of a SingletonClosure is always either a single item
or an empty sequence.
<p>The expression may depend on local variables and on the context item; these values
are held in the saved XPathContext object that is kept as part of the Closure, and they
will always be read from that object. The expression may also depend on global variables;
these are unchanging, so they can be read from the Bindery in the normal way. Expressions
that depend on other contextual information, for example the values of position(), last(),
current(), current-group(), should not be evaluated using this mechanism: they should
always be evaluated eagerly. This means that the Closure does not need to keep a copy
of these context variables.</p>
