oldStm to the stream.
oldStm should be written entirely
in terms of the callers environment, i.e. the
target and all arguments should be part of the
object graph being written. These expressions
represent a series of "what happened" expressions
which tell the output stream how to produce an
object graph like the original.
The implementation of this method will produce
a second expression to represent the same expression in
an environment that will exist when the stream is read.
This is achieved simply by calling
on the target and all the arguments and building a new
expression with the results.
