[Octave-bug-tracker] [bug #33217] Matlab's try, ...; catch EXCEPTION, ...; end doesn't work (no support for caught error)

[Gokberk]

Follow-up Comment #1, bug #33217 (project octave):

I think this is an important compatibility issue. 

my_caught_error() is a nice idea but it is rather risky. If there are more
than one try-catch block in a workspace, it will not work properly unless the
user is careful enough to clear my_caught_error. For example:

try,
    TRYBLOCK_1;
catch my_caught_error;
    CATCHBLOCK; % using my_caught_error instead of lasterror
end

try,
    TRYBLOCK_2;
catch my_caught_error;
    % my_caught_error is not valid, it is still the error structure generated
at TRYBLOCK_1.
end
