A Statement
object represents a primitive statement
in which a single method is applied to a target and
a set of arguments - as in "a.setFoo(b)"
.
Note that where this example uses names
to denote the target and its argument, a statement
object does not require a name space and is constructed with
the values themselves.
The statement object associates the named method
with its environment as a simple set of values:
the target and an array of argument values.
