It bothers me that majority of languages ignores a nice python approach. `', '.join(any_str_iterable)`. Instead of supporting join for myriads of containers there is a single str method.

Python's approach is one of the most confusing ways to possibly do it. Not having proper, discoverable methods is super annoying, and I need to look it up every time anew I use Python because it's so unintuitive.

Of course you can write a generic version of `mkString` (as this method is called in Scala), so it's also just one method no matter the container count.

The Python weirdness is actually a direct result from the language lacking generics…

From typing perspective there is no sense to have Container[T].join() -> str for any T.
