That's the point. Proper Tail Calls allow you to write code that is otherwise *i... jwmittag (Jörg W Mittag)

07:58 AM Ruby Feature #16095: 2 Features: remove (simplify) 'new' keyword and Property Shorthand

Please, do not mix requests for multiple unrelated features in one feature request. It makes it impossible to properly address them. For example, what should happen with this feature request if one feature gets accepted and one gets reje... jwmittag (Jörg W Mittag)

08:46 PM Ruby Feature #14701: If the object is not frozen, I want to be able to redefine the compound assignment operator.

a ω= b
```
