Re: [go-nuts] go get failing In Mac 10.11.4

My guess is that's because Mac filesystem is case preserving but not case-sensitive, meaning that in mac os "floRest" and "florest" is the same file/directory while on linux those are 2 distinct files. (you can configure mac filesystem to be case-sensitive as well, but that's not the default).

[go-nuts] Re: A proposal for generic in go

I think I have to agree with most of the posters here about generics. In theory, I miss them. However, in practice, I find that there are usually only a few times during the course of a project where I wish I had generics. And then after writing a few lines of code to do what the generic

The issue is, that a "KeyValuePair" (no matter if you implemented it via generics or like you mention via interfaces) is a fundamentally useless type and generics encourage people to add useless types. A "KeyValuePair" is a "struct { Key K, Value V }", plain and simple. It's not an

You still haven't provided any argument why generics is indispensable. The reason why I am no longer sure about my position in this issue is because -while I agree that generics is useful- I don't think that generics is essential. In fact, all of C++ features are useful and implemented in a
