--- Comment #2 from Michael Gratton <mike at vee.net> ---
So I've just found `jsc_context_get_exception` and `jsc_context_clear_exception`, which helps (just)! There are some problems with this however:

 1. It is racy between invocations
 2. There's no documentation about when it's valid to call either method, if the latter needs to be called and if so, when
 3. There is no documentation to suggest this is actually useful for the use case above
 4. No members are ever set when this object is non-null due to an exception being thrown after call to `jsc_value_object_invoke_methodv` - name, source-uri, etc are always null, line and column numbers are always 0 (they're not even -1, since these are uints)

So aside from the fixes needed for (2)-(4), consider this a feature request for an API that doesn't have the limitations of (1). Thanks!
