Less than 24 hours later we saw the first comment about generics. - https://blog.golang.org/why-generics https://blog.golang.org/why-generics But it's just taken that long to come up with a good design. Most of the work has been pushed forward by core team member Ian Lance Taylor who put forward the case in https://github.com/golang/proposal/blob/master/design/15292-generics.md https://github.com/golang/proposal/blob/master/design/15292-... This abstract proposal has been updated to link to a summary of concrete proposals at the footer, ""presented for historic reference. All are flawed in various ways"" Type functions (June 2010) - https://github.com/golang/proposal/blob/master/design/15292/2010-06-type-functions.md https://github.com/golang/proposal/blob/master/design/15292/...
