Folks,

For reference, I believe the bindings should behave specially
for GDALOpen and OGROpen and that they ought to *not* through
an exception even if an error was set as long as the function
returns a non-NULL pointer.

Unfortunately I find the bindings logic challenging at times,
and I don't want to step on the toes of the bindings maintainers,
so I have not tried to apply my approach.

I agree with the poster who suggesting having an "ignore errors"
flag for open isn't a great solution.  It just further complicates
something that doesn't really need to be complicated.

Best regards,
