No, because, as you state yourself, equality is not something that everyone
defines the same way.

Your requirements for a single Element are simple enough to write it in three
to five lines of Python code (depending on your definition of equality).
Checking this equality recursively is another two to three lines. Not complex
enough to be considered a wheel in the first place.
