Daniel is a fan of this syntax, but I think it is inferior to the implied approach, so don't expect it to survive to any accepted version of the PEP :)
Another thing against ~= is that it isn't valid Python syntax. It's not a deal- breaker, but it does mean that you can't e.g. use the ast module in the implementation. This might be a factor if the mini-language ever grows (as it recently did, adding parentheses).
