Motivation

Solution

Hey @mattsse, could I please ask for help on the following 2 questions:

1. Feedback on this approach of creating another method. This was to avoid the use of interior mutability which would've allowed for mutation under a &self API. Introducing interior mutability seemed like a much larger and riskier uplift.
2. I would also appreciate any insights on why this particular test fails at https://github.com/EdwardJES/foundry/blob/cd56aa00c8fa4fbab452efa3751bbf58d89b806e/crates/anvil/src/eth/backend/mem/storage.rs#L565, where the acc can't be found.

Thank you very much.
