--- Comment #1 from Adrian Perez <aperez at igalia.com> ---
Currently we do not have any hint in the API documentation
about this. Basically: whether the exception is cleared or
not by jsc_context_evaluate_* is undefined.

I think that the proposal makes sense, but technically that
implies changing the behaviour of existing public API. To me
it looks unlikely that we would break applications with the
change: I would expect that applications that check for
exceptions after calls to evaluate JS code are already calling
jsc_context_clear_exception() and doing that implicitly at the
beginning of jsc_context_evaluate_* functions will just be a
no-op for those apps; and in the other hands new applications
can use the API in a more convenient way.

As this would be a change in the behaviour (even if small)
I think we need to be careful. I have CC'd Carlos García to
have a second opinion on this.

At any rate, thanks for the suggestion!
