This is a fine stopgap.  In the long run, we need:

(1) Documentation (for all exception classes).
(2) Better constructors (e.g., IAE  should take a parameter describing what was
expected, as well as what was found.
(3) Better code style (e.g., state variables before functions, comments
describing state variables, etc.)

What is our normal style in library code, if we don't want to specify a type do
we use 'var'
e.g:
final var _arg;

I recall that it didn't let me use "var" here, but perhaps I'm remembering
incorrectly.
