I would go with option C, even though there's a bit of repetition 
of the symbol's (return) type. Potentially the text on the right 
could be changed to something else that provides more information 
(e.g. `pkg.module`, visibility (`public`, `package`, etc.), if 
it's a parameter / local variable whether it is `return` and/or 
`scope`, etc.), built-in function attributes, UDAs, etc.).
