Backpack doesn't work with Template Haskell, even when it should
Obviously, we can't run Template Haskell from an indefinite package when we are (solely) typechecking the indefinite package itself. But in principle, Template Haskell code from other packages should be fair game.
Alas, this not the case, because GHC attempts to dynamic link in libraries for ALL dependencies, including the ones we don't have code for. Quick fix should be to not link those in?
