*Disclaimer*: This is intended for discussion My impression is that the with-exceptions backend is to be superseded by the without-exception backend, which is more general and more efficient. Therefore, seeing the added complexity of maintaining the two in parallel, I see no good reason to keep the with-exceptions version now that the equivalence of their semantics have been proved. It will also be nice to reduce divergences between the different backends ; and this should make further simplifications possible (e.g. some thunkings may no longer be needed) Of course I am ready to hear arguments in favor of keeping it, be it in the mid- or long-term. This patch removes the `--avoid-exceptions` flag, making it the only option, and the corresponding `with_exceptions` variant of the dcalc->lcalc translation. It doesn't do further simplifications.
