Re: [go-nuts] Re: Why + and += operators for string but not slices?

The thread already shows several alternative interpretations which are different from that. Go tries to avoid constructions that require careful specification of that sort. Append already causes enough confusion, but that's important enough that dropping it would be a loss. + for slices is only

The values of the summation are indeed unambiguous, but the data aliasing properties are not. On Fri, Sep 16, 2016, 12:58 PM wrote: > Thank you both. > > To Ian: but a slice is not a matrix or a list. > > To Axel: append() and copy() compliment indexing and slicing well

Don't confuse variadic arguments with slice arguments, by the way. On Wed, Aug 3, 2016 at 8:20 AM T L wrote: > > > On Wednesday, August 3, 2016 at 10:53:34 PM UTC+8, Jessta wrote: > >> On 4 Aug 2016 12:36 a.m., "T L" wrote: >> > >> > Often, I need

Re: [go-nuts] Plurality of package naming

That's advice for a very different style of language than Go. Go does not have "objects" in the sense of that post. A Go interface, for example, does not "have lots of instance variables, lots of arguments, and pass lots of data around probably." A class is not a struct is not a Go interface.

Re: [go-nuts] Interface{} constrains on specific types

The trick is to do this: Decl special_interface and then special_interface requires an unexported interface which you implement in the specific (new) types that you can store in the thing. On Fri, Jun 24, 2016 at 3:10 PM 'Mihai B' via golang-nuts < golang-nuts@googlegroups.com> wrote: > I'm
