Bad idea IMHO. Exceptions and their stack traces can still be logged in release
builds, which can be useful when a customer has an issue.

The results of your experimentation sound promising though.

That would definitely be cool. Having fast exceptions would be a huge boon
IMHO, since code written with exceptions is generally much cleaner, and if we
can generally use exceptions in performance-critical code, then we can
generally have cleaner performant code. There will probably always be code that
will need to avoid exceptions for one reason or another, but if we can make it
so that their negative impact is minimized, that would be fantastic. Right now,
it's pretty bad.
