## Why this should be merged Adds logging of `libevm` modification of default behaviour. ## How this works 1. Introduces `log.Lazy` functions to allow expensive logging operations to be computed i.f.f. required by the logging level. 2. Adds `Info` logging for registration of types and `Debug` logging for all else. 3. Only paths that change behaviour in a potentially unpredictable manner are logged; of note, RLP / JSON encoding is _not_ considered unpredictable given that registered extras are logged. 4. The minimal viable package, `set`, was necessary because we don't want to depend on `avalanchego` and the `hashicorp/go-set` latest version requires a later version of Go. #153 tracks a swap to the latter when possible. The `eth/tracers/internal/tracetest` test flaked at least twice (unrelated to these changes) so I've marked it as such since it's not worth a separate PR. ## How this was tested New unit test on `log.Lazy` + `set` methods. Existing CI for the rest as it's a refactor.
