 but perhaps in practice it won't come up.  (Because writing Thun code by
 derivation seems to lead to bug-free code, which is the kinda the point.)

Variations between Interpreters

+
There are several small choices to be made when implementing a Thun
+interpreter (TODO: make a comprehensive list), for example, the Python
+interpreter keeps all of its functions in one dictionary but most of the
+other interpreters have a case or switch statement for the built-in
+functions and a separate hash table for definitions.  Additionally, of
+the interpreters that have hash tables most of them check the hash table
+after the case statement.  This means that one cannot "shadow" built-in
+functions in some interpreters.  You can inscribe them, but the
+interpreter will not look for them.

+
I haven't yet formally made a decision for how Thun shall work.
+Letting built-ins be shadowed is fun and useful for exploration, and
+letting them be inviolate is useful for unsurprising behaviour.

+
Another choice is how to handle duplicate definitions in general. Should
+you be able to reuse a name?  Or should inscribe throw some sort of
+error if you try?
