Thanks for this! gctx.shell() is tricky, and I have shot myself in the foot with it many times (most recently when working on the linting system). I think removing bindings from it everywhere is a good idea.
Do you think it would be a good idea to add a test for this?

I lean toward not. Such a test cannot systematically prevent this kind of runtime borrow checking bug. |

This intentionally borrows from `RefCell`s before conditional code to try to prevent regressions like rust-lang#13646 without exhaustively covering every case that could hit these `BorrowMutError`s with complicated tests. I tested this by ensuring the registry code path panicked before rebasing on top of rust-lang#13647. Once I rebased, the panic went away.
