And let's then propagate that notion, to a coherent definition of split that makes it as well a method on the separator.

Let's not.

Splitting is not something that you on the separator, it's something you do on the source string. I'm sure you wouldn't expect this:

":".find("key:value") => 3

Nor should we expect this:

":".split("key:value") => ["key", "value"]

You perform a search on the source string, not the target substring. Likewise you split the source string, not the separator.
