I found exception to be a mess both for exception-incapable languages (like
C), which is not a surprise. I found it also rather inconvenient for
exception-capable, as we anyway have return values.

My plan was to:
1/ get rid of the exception error code as it is nowhere used,
2/ use the return value of the function for error signaling,
3/ provide a per-thread error message to convey what's currently in the
exception.

Then, I'll remove exception completely. It's up to each bindings whether
they want to the convert error return and the error message into an
exception, or use a purely functional model.
