Go: Support for multiple return values

[robskie]

Will multiple return values be supported for Go?

[Maratyszcza]

No plans for that

[robskie]

Ok.

[Maratyszcza]

Please leave the issue opened. Probably somebody else would want to implement it.

Documentation:

Multiple return values in Go are passed on the stack after the arguments. They are addressed relative to FP. It seems that RETURN could be special-cased to take a tuple or a list, and then just assign to successive slots.

@Maratyszcza @dgryski it would be great if it is supported. I want to write the sum of int64 slice with int64 overflow check. func AddInt64Slice(s []int64) (int64, bool) bool here will return if the overflow happened or not. In the meanwhile, is there a workaround for getting multiple return values from the function? is it possible to have dummy int64 slice as a function parameter and store the result like [int64sum, overflowstatus(0/1)]?

@siddhesh503 avo supports multiple return values (but of course requires that you port your asm code from peachpy to avo).
