Allow the user to customize the evaluation/execution of expressions/
statements with something that implements functions that perform
those tasks. This additional functionality will make it possible for
the "classic" evaluator not to waste time checking for the presence
of interlopers and give implementers additional customization opportunities.

Centralize the execution of statements and evaluation of expressions
so that the user can specify a debugging "callback" after every
execution/evaluation.
The callback can be used for myriad things, but it seems likely that
it will be useful for implementing:
1. Testing
2. Debugger

When a function is called, if there is an (in)out parameter,
make sure that updated values are propogated to the calling
function.

The type system (and the value system) now include attributes
for each type (things like direction, const-ness).
