Greetings,

a colleague of mine who recently started to learn Ruby managed to greatly confuse me today when he used Set#delete? which he claimed would delete an item from a set.
Reading the documentation I suspect the method was meant to be named delete! as it behaves similiar to Array#uniq! and such methods.

If this is not a mistake, I'd still suggest to change the method name since I think it is very surprising for a method ending in a question mark to have a side effect.

Best regards,
Kai
