It depends on how approachable a feature is. Is it self-explaining or cryptic. Easy or hard to explain and understand. Obvious to google even when you not know the name for it. In those regards most new python 3-features are more on the good side. I know how often I googled for old python features like string substitution (the %-thing) or list comprehensions (the loop inside []) and I just could not figure out and remember the names, because % and [] are simply not self-explaining.
