[Python-ideas] Re: Make ~ (tilde) a binary operator, e.g. __sim__(self, other)

I am not yet a contributor to either, I have an invitation to contribute to Sympy, and I have contributed to CPython, and I would like to be a contributor on all of these libraries (You might know me from my answers on Stack Overflow, and I gave the slots talk at PyCon 2017 where we met - now I'm also in weekly meetings with my employer to open up and green-light FOSS contributions for employees - it's really only fair as we use FOSS extensively...) My first inclination is to translate Patsy's `a:b` to `interaction(a, b)`, but to me that's a tertiary concern. My main goal here is to increase the flexibility of Python for various domains where I have used `object0 ~ object1` - and can't yet do so in Python.
