So the benchmark would not really test much - besides checking that var handle access is slow when `asType` cannot inline. What I was trying to do here was to avoid `asType` being inlined into that `compileAsType` method - but I agree that the annotation I added isn't it.

I think EXCLUDE would work, yes. True about CompileCommand having a global effect, so that won't work. (With a CompilerDirective file we could be more precise, not sure if it's worth it though).
