Well, if we can change it so that whether the contracts are run or not is
determined by the caller and not the callee, then using them would
definitely be worth it. But as long as that's not the case, it's not at all
worth the visual noise IMHO to use in and out blocks IMHO. And if/once we
change it so that whether the in and out blocks are run is determined by the
caller, the visual noise will still be annoying enough to make it so that I
won't be in a hurry to add them unless they're adding real value rather than
just some additional, nice-to-have checks.
