Contributions summary:Robin primarily contributed to the implementation of string manipulation methods within the Ruby interpreter, specifically `tr`, `tr!`, `tr_s`, and `tr_s!`. These changes involved modifying the `rupypy/objects/stringobject.py` file to include the core logic for string transformation and the `tests/objects/test_stringobject.py` to add associated tests. The commits demonstrate a deep understanding of string object internals and a focus on enhancing the Ruby interpreter's string handling capabilities.
