Yeah, that seems like such a disproportionately heavy cost.
Does it make sense?
I haven't though through the details, but if it can be done, I
think it would be nice. I like when programming tools are more
intelligent about things like this because after you become
familiar with it and build confidence in it, you can just code
your ass off and know that the compiler is doing right on your
behalf.
