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.
