Did Julia community do something to improve its correctness?

For those interested, I’ve opened a separate thread about the feasibility of adding multiple inheritance to Julia:

Feasibility of adding multiple inheritance to Julia

The topic of interfaces came up again in one of the correctness threads. My minimally informed opinion is that the best solution would be to add multiple inheritance to the language. How feasible would it be to add multiple inheritance to Julia? I’m sure it would be quite a bit of work, but my question is not about the amount of work required. What I am wondering is how feasible it is to add multiple inheritance from a language design perspective.
