If you need to know which member of enum that particular instance 
of a struct is, that has it's method invoked, then you could 
check for this
inside function body of said method, by looking to which enum 
member this instance is identical to by either memory address, or 
equality.

Btw there should not be any problems with self reference in case 
if you have enum type as an argument to a method inside struct 
imho.
