I find it hard to believe. Since a huge class of errors are caught by compile time static analysis, you don't really need an exception system, and errors are basically just return values that you check.

It's much more productive just to use return values and check them, wrap return values in an optional, do whatever. Just move on, do not recreate the features of your previous language on a new language.
