regress in Run-time errors on objects no longer fatal?

[Inververs]

Autoit 3.3.9.0 has Changed: Run-time errors on objects no longer fatal (execution of the script is not halted). 
And it work in 3.3.12.0
 
But in beta 3.3.13.19 script ended with error  The requested action with this object has failed
 
Or maybe this is Script Breaking Changes?
 

$a = ObjCreate('scripting.dictionary')
$a.add('x','a')
ConsoleWrite(@error & @CRLF)
$a.add('x','a')
ConsoleWrite(@error & @CRLF)

Yeah, the change is intentional. Jon had a post about that some time ago giving explanation and basically redefining the word "stupid". However, I hope people that influence Jon these days will be smart, and more importantly eloquent, enough to make him reconsider the decision.

I also hope for peace in the world. How big are chances for that?

Inververs,

Other than the intentional nature of the change, I completely refute the version of events in the post above - it is nothing more that the usual bitter and twisted personal attack we have come to expect from that member. >

Jon made a design decision - his privilege - and as a matter of fact there was a fair amount of opposition expressed. His argument was basically that AutoIt should not silently accept script errors and so hide their existence from the user. You can get round the problem very easily by creating your own simple error handler like this and registering it every time there might be a problem:

$a = ObjCreate('scripting.dictionary')

; There might be a fatal error in the following code, so prepare for it
Template_COMErrorRegister()

$a.add('x', 'a')
ConsoleWrite(@error & @CRLF)
$a.add('x', 'a')
ConsoleWrite(@error & @CRLF)

; Fatal error section ends, so no further protection required
Template_COMErrorUnregister()

; ----------------------------------------------------------------------

Func Template_COMErrorRegister()
    Global $__g_oTemplateCOMErrorHandler = ObjEvent("AutoIt.Error", "Template_COMErrFunc")
EndFunc   ;==>Template_COMErrorRegister

Func Template_COMErrorUnregister()
    Global $__g_oTemplateCOMErrorHandler = 0
EndFunc   ;==>Template_COMErrorUnregister

Func Template_COMErrFunc()
    ; Do nothing, just check @error after suspect functions.
EndFunc   ;==>Template_COMErrFunc

In fact the change has already proved useful. We recently discovered by chance that scripting dictionary objects do not accept 64-bit keys - but as in the past AutoIt failed silently on the error, the user was not informed and so got an empty return when using _ArrayUnique. I rewrote the function to get around this problem and I have added an error handler like the one above to cope with the case of an Int64 being passed inadvertently as a key.

trancexx,

You have been warned before about making ad hominem attacks when commenting on AutoIt development. By all means disagree with decisions - as many did with the one under discussion - but remember that it was your decision to resign as a developer which means you now have no role in the development process. As you seem incapable of restraining your impulse to make it personal whenever you post rather than applying your undoubted talent to the benefit of the community you will be unable to do either for a while.

Unfortunately this means that we all lose - but your actions leave little choice. You cannot expect to remain welcome in a community upon which you so often inflict your vitriolic attacks. >

trancexx, Melba23, thank you. Clear.

I know about ObjEvent ("AutoIt.Error", "func"), but even so, thanks for the example and for the fact that you reply in such detail.
