Hey, so I tried porting our code to compile with latest nightly and I almost got it working but ultimately it ended with an internal compiler error:
error: internal compiler error: compiler/rustc_trait_selection/src/traits/codegen/mod.rs:121:9: Encountered errors `[FulfillmentError(Obligation(predicate=TraitPredicate(<dyn sc_client_api::PrunableStateChangesTrieStorage<sp_runtime::generic::Block<sp_runtime::generic::Header<u32, sp_runtime::traits::BlakeTwo256>, sp_runtime::OpaqueExtrinsic>> as sp_state_machine::changes_trie::Storage<sp_runtime::traits::BlakeTwo256, u32>>), depth=0),Unimplemented)]` resolving bounds after type-checking

I created a branch that fails with this or a similar ICE when you run cargo test --all. You can find it here: https://github.com/paritytech/substrate/tree/bkchr-fix-for-latest-nightly
