As reported by vsevik@ (thank you), the change causes several warnings.

Source/WebCore/inspector/InjectedScriptSourceTmp.js:600: WARNING - Bad type annotation. Unknown type integer
     * @param {integer} scopeNumber
               ^
Source/WebCore/inspector/InjectedScriptSourceTmp.js:618: WARNING - Property setFunctionVariableValue never defined on InjectedScriptHost
            setter = InjectedScriptHost.setFunctionVariableValue.bind(InjectedScriptHost, func); 
                     ^
Source/WebCore/inspector/front-end/protocol-externs.js:2085: WARNING - optional arguments must be at the end
DebuggerAgent.setVariableValue = function(opt_callFrameId, opt_functionObjectId, scopeNumber, variableName, newValue, opt_callback) {}

vsevik@, could you please take a look at the patch.

Note that in order to satisfy requirement that optional parameters go last, I tried to reorder parameters in Inspector.json, those ones that originally were first, but recently became optional.
I'm not sure though, that we can afford reordering parameters.

Can you provide a test for this command?

I thought LayoutTests/inspector-protocol/debugger-setVariableValue.html was that test.

Oh, I see. I meant that it would be nice if we had a test that would require changes in accord with your concern https://bugs.webkit.org/show_bug.cgi?id=109488#c2

That's right. But so far we don't any client that depends on parameter order. I don't think we should prepare such client only to prove that parameter order in fact changed.

However, I wonder if we should change parameter order. For example Java project bindings depends on order and theoretically such changes might go unnoticed unless caught by parameter type checks.
