Hi all.
Is there a way to get function's name?
(define (fn) ...)
How can I retrieve "fn" inside itself body?
You can use object-name to get the name of a function, if it has one.

#f
There's no way to ask "what function am I in?"; you have to handle
getting a reference to the function yourself. That's no problem with
defined functions, though, because the function name is in scope within
the function's body:

"I am called fn."
