Hi!

That might be a bit harder to do. __toString does not throw because it's
used in many contexts inside the engine where you can't just drop what
you're doing and start processing the exception - like in the middle of
function accepting parameters, or in the middle of calculating the
expression, in the middle of executing a function call, etc. I'm not
saying it's impossible to do, but it would require adding a lot of very
carefully written code so that interrupting whatever the engine was
doing is safe, and even then not clear what to do with extensions which
won't have this code.
