Andrei Alexandrescu Wrote:I'd like to have an easy enough syntax for defining read-only properties (often in my code). With the proposed syntax, one writes bool empty { ... } and calls it a day, but with the elaborate getters and setters there are two scopes to get through: bool empty { auto get() { ... } } which is quite some aggravation.
How about syntactic sugar for this? Let's have two types of property declaration 1. Regular property. Only op* functions allowed inside, no field declarations, no normal functions. bool empty { opGet(); opSet(); } 2. Concise readonly property. Only procedural statements allowed inside, op* functions are disallowed. bool empty { if(length==0)return true; } 3. It's not quite an aggravation to declare a readonly property. bool empty { opGet(); }
