-// For asserts we'd like to keep all the junk executed when an assert happens away from the
-// important code in the function. One way of doing this is to put all the relevant code inside a
-// lambda and force the compiler to not inline it. Unfortunately, MSVC seems to have no syntax to
-// specify __declspec on lambda functions, so what we do instead is define a noinline wrapper
-// template that calls the lambda. This seems to generate an extra instruction at the call-site
-// compared to the ideal implementation (which wouldn't support ASSERT_MSG parameters), but is good
