Hi, Question about the receiver of a func.
It can be defined as star/no star, and consumed as star/nostar. The understanding i have so far is, it let the developer define the memory model he d like to use. It leads to cases such as - define start/nostar on a type - consume a stared type as a value - consume a value type as a pointer Which is quiet confusing for beginners, and me. While i understand that someone would like to declare a type is consumed by value, I do not understand the last two cases. when why they might happen. Can you explain their value added ? Thinking further more, Not speaking about dereferencing a pointer, but initialization of a type in a way that is undesired to the provider. The way a type is consumed by value or reference, is an act of design rules (i add a property on the type that make sure it is never copied/referenced) or an act of consumption, the designer did not enforce any rule on the type, i might initialize it as star/nostar at convenience. The fact it is let possible today - to not enforce the way a type is manipulated, leads to confusion and error (famous one is https://godoc.org/sync) - to define at both declaration / usage the star/nostar, is confusing, again so yeah, wondering quiet a lot about that, and given the fact i do not understand few use cases, i think this could be better handled. For example, if a new keyword appear to ensure a type is consumed by value, that might be helpful to provide a function to make sure that type won t exceed the stack size and escape to the heap. that keyword would help api designer to avoid consumption problems. nop ? If a new keyword would appear to ensure a type is initialized by reference, might help to detect value copy and warn/error when that case is met. That would helped consumers to avoid problems. nop ? If the receiver type was not able to be star/nostar, that d probably help to get ride of confusion, nop ? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
