Looking at trait conformance, callee contracts have two different paths.
They can either be "compatible" with a trait by defining methods
matching some of the methods defined in a trait, or explicitely declare
matching some of the methods defined in a trait, or explicitly declare
conformance using the `impl-trait` statement:

```scheme

Explicit conformance should be prefered when adequate.
Explicit conformance should be preferred when adequate.
It acts as a safeguard by helping the static analysis system to detect
deviations in method signatures before contract deployment.
