Hey @Galileo-Galilei, I've made the changes to address the issue in (#73). I've implemented your proposed solution, which works for now. The code could use some additional tests (e.g., testing other arguments of validate method) and refactoring , but I currently don't have enough time to do that.

Thank you very much for the PR. I'll have a look by the end of the week, and release a new version to PyPI as soon as it is merged.
