Looks good to me. I ran a full test on Linux with the default dynamic libraries and all looks good. I also tested that the `resource` protocol throws an informative exception:

I asked one question, but whatever you decide is fine with me.

Is it always going to be the case that STATIC_BUILD == is SubStrate VM?
