For example, I have worked on systems with trillions of records. Many on this list - and in particular, on the Go team - are in very similar boats. I don't say this to brag - but just to clarify, that a lack of experience with scale is not generally what informs opinions here. I don't really think your suggestion is a priori more efficient, FWIW. There is no reason the compiler actually *has* to insert function calls, and given that your suggestion is semantically equivalent to splitting the code into multiple functions (and that is the most likely way it would be implemented - after all, with the GC, defer and other features, you can't just jmp into the middle of a function anyway), I feel it's hard to justify why it would be more efficient without actually looking at a finished implementation (and weighing that against putting that effort into better compiler-optimizations). In any case - I don't think efficiency can or should really drive the discussion. > > Warren > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/golang-nuts/d55e9c5d-6d07-4c91-92c6-a3c3060790bf%40googlegroups.com > <https://groups.google.com/d/msgid/golang-nuts/d55e9c5d-6d07-4c91-92c6-a3c3060790bf%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
