Hi @willmcgugan, could you please take a quick look at this one?

[willmcgugan]

Can't accept this I'm afraid. I'm assuming you want to monkey patch get_repr?

Monkey patching isn't good API, but if you are comfortable with it, you could just do this:

globals()['repr'] = lambda obj: "foo"

That said, I think the best approach right now would be to write a method that accepts your objects and returns a proxy with a __rich_repr__.
