Questions

<span class="quote">&gt; Source/WebKit2/ChangeLog:12
&gt; +         - Use Function instead of std::function on dispatch methods.</span >

Why, just to use our thing instead of the standard one? Is there an advantage to WTF::Function?

<span class="quote">&gt; Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp:44
&gt; +    RunLoop::main().dispatch([protectedThis = makeRef(*this), function = WTFMove(function)] {</span >

Why is this correct? We don't use |this| inside the lambda, so why the need to keep it alive? If the ref is really needed then it should be handled inside |function|, right?

<span class="quote">&gt; Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp:56
&gt; +    m_clientRunLoop.dispatch([protectedThis = makeRef(*this), function = WTFMove(function)] {</span >

Ditto.

<span class="quote">&gt; Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp:158
&gt; +    dispatchOnClientRunLoop([this] {</span >

Why no protector?

<span class="quote">&gt; Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp:622
&gt; +    dispatchOnMainThread([this] {</span >

Ditto.

<span class="quote">&gt; Source/WebKit2/Shared/CoordinatedGraphics/CoordinatedGraphicsScene.cpp:689
&gt; +    dispatchOnMainThread([this, layerID, offset] {</span >

Ditto.</pre>
