send accepts both a string or a symbol. The documentation for Object#send, 
states

object.send(symbol, [args...])

and the documentation of Object class, says:

In the descriptions of Object's methods, the parameter symbol refers to a 
symbol, which is either a quoted string or a Symbol

Besides, your own code passes a string to send, since funk.to_sym returns a 
symbol, but doesn't change what is stored inside funk, so when funk is passed 
to send, it still contains a string.
