An expression is a snippet of code that can be evaluated
to produce a value. When and how an expression is evaluated
is implementation specific. The context/binding required to
evaluate an expression varies by debug model, and by
user intent. Furthermore, an expression may need to be evaluated
at a specific location in a program (for example, at a
breakpoint/line where certain variables referenced in the
expression are visible/allocated). A user may want to
evaluate an expression once to produce a value that can
be inspected iteratively, or they may wish to evaluate an
expression iteratively producing new values each time
(i.e. as in a watch list).
Clients are intended to implement this interface.
