+ "Note that #literalsDo: is faster than #hasLiteral: (and #hasLiteral:scanForSpecial:). We already know that 'self deprecated' should be the first statement in a deprecated method, which is directly accessible in this method's literals. No need to check compiled blocks or other nested structures.

+ Note that both #isQuick and is-this-method check make no sense performance-wise. Maybe bench again in the future."
