rust event system type erasure

	/// calloop = "0.10.5"

	/// TODO: in the current implementation when you add a new handler
	/// inside another handler
	/// and then emit an event before all handlers have been called
	/// the new handler will be called twice
	/// gotta think about how to fix that

	; challange:
	; --------------------
	; Challenge #3
	; --------------------
	; Caesar Cipher
	;
	; You may know also this as ROT N.
	; Your solution should input an arbitrary ROT cipher encoded string and output all shifts.
	; The allowed alphabet is [a-zA-Z] any other characters are not shifted and output as is

the legendary python switch case

	# or maybe the key could be a callable too which will return true or false
	# that kinda would just be an if tho
