🚨 fix linting warning (rule B019)

[DavidRomanovizc]

What was wrong?

The codebase currently use the lru_cache decorator in the NodeVisitor and ABIRegistry classes over methods. The flake8-bugbear linter reported a B019 warning, indicating potential memory leaks in class methods. The lru_cache decorator retain instance references, impeding garbage collection and potentially leading to memory-related issues.

Related to Issue #218
Closes #218

How was it fixed?

We don't have to replace lru_cache with something else for solve linter warning. This problem can be solved in the following way: we stopped using decorators directly over methods. Instead we apply the decorator function when initializing a class instance.

Todo:

• Clean up commit history

• Add or update documentation related to these changes

• Add entry to the release notes
