In practice I've not found ':' to be any less error prone. It's easy to accidentally type '.' in its place so you are trading one mistake for another.

In practice though, after you have dropped the magical self notation and start thinking outside the realm of objects and classes, you began to wonder why you ever needed ':' in the first place. It begins to feel very artificial to have one biased function arg when you really just have functions operating on its args. Also not needing to shoehorn every operation into a class, was a real eye- opener for me.
