Looks great. I remember one example from one of the std::function patches that was taking a bool that I don’t see you changing back here.

Could add a unit test for this too since we have Function.cpp now.

My fault you added this, but it’s not compiling on Windows, maybe due to the different flavors of function pointer that exist on Windows.

Same here.

Somehow Windows requires the explicit WTF::Function<void (bool)> { } here.

This change broke the Windows Debug build:

I really need to find a way to make Window build without this. This is ugly :/
