Sorry, Golang 2 likely won't include your "missing" feature

Presently is your opportunity to request new Go highlights, however Golang's traditionalist outline logic will probably keep changes to a base

The authority Golang blog has given the principal solid insights about the following rendition of Google's Go dialect, which is utilized to make prevalent applications like Docker and Kubernetes, and also to incrementally supplant basic web framework. 

Be that as it may, Golang devs sitting tight for quick word about generics, or other pet elements they've for some time been holding up to see added to the dialect, will leave disillusioned. 

The post, composed by Golang planner Russ Cox, subtle elements how the central objective for Golang 2 is "to settle the most noteworthy ways Go neglects to scale." By "scale," Cox is alluding to both creation and advancement. The previous is about "simultaneous frameworks associating with numerous different servers, exemplified today by cloud programming," and the last is about "substantial codebases chipped away at by many designers organizing just inexactly, exemplified today by present day open-source advancement." 

Some portion of meeting the second objective, scaling to vast groups, includes guaranteeing that current Golang designers and codebases are not abandoned. "Blended projects, in which bundles written in Go 2 import bundles written in Go 1 and the other way around," composed Cox, "must work easily amid a move time of different years. We'll need to make sense of precisely how to do that; mechanized tooling like go fix will absolutely have an impact." 

Different dialects have encountered significant developing agonies between updates when they presented changes that weren't entirely in reverse perfect. For instance, Python 2 and Python 3 have basically a similar grammar, yet enough contrasts to shape a noteworthy crack between the two forms of the dialect. 

One conceivable component, generics, has been a list of things to get thing of some Go engineers, who assert it will make certain programming assignments more straightforward. In any case, the Golang group has reliably communicated hesitance to incorporate generics, in light of the fact that presenting it may confound the dialect in ways its originators need to dodge. 

Cox said generics specifically in the blog entry, yet encircled the talk around them regarding how any new dialect include needed a solid utilize case connected to it. In his view, any such expansion should be driven by particular certifiable situations—what Cox called encounter reports. 

"I don't have in my mind a reasonable photo of the nitty gritty, solid issues that Go clients require generics to unravel," Cox composed. "Therefore, I can't answer a plan question like whether to help non specific techniques, which is to state strategies that are parameterized independently from the recipient. On the off chance that we had an extensive arrangement of true utilize cases, we could start to answer an inquiry like this by inspecting the huge ones." 

Approximately three camps have created in the Golang people group around the subject of generics. Some trust the dialect doesn't really require them, on the grounds that current dialect highlights handle a large number of a similar utilize cases. Others have amassed different workarounds, generally by method for Golang elements, for example, interfaces. In any case, a third unforeseen demands that including generics would make it far simpler to work with an entire class of issues in Golang. 

The Golang group's expressed arrangement is to evade breaks in the dialect on account of such significant changes, and to just present such things "when the reward is awesome." Such objectives supplement Golang's remaining as a dialect for building framework that is manageable and viable, with code that is as yet intelligible and usable decades down the line. Yet, that likewise implies the vision for the dialect from its makers as often as possible supersedes the requests made on it by its clients.
