Brent,
The ReadWriteStream is a bit confused about how much there is available to read. Try this instead:
-----
| exprStream result failBlock |
exprStream _ ReadStream on: '1 + 2'.
failBlock _ [ Transcript show: 'ArithmeticExpression#eval FAILED: ', exprStream contents. ].
result _ Compiler new evaluate: exprStream in: nil to: nil notifying: nil ifFail: failBlock.
^ result
-----
Cheers,
Bob
