Re: [go-nuts] Unary +

With all due respected to the illustrious Dr. Iverson, he was in loony-land with his two versions of minus. The notation "-3" does not mean "negative three", which, as my freshman math professor, a lover of English, pointed out, is a solecism, since "negative" is an adjective, and three is and

[go-nuts] Remove vs Delete

I have always considered add/remove to be a pair of keywords and insert/delete a pair of keywords so you could look at the method name used to place the item in storage originally I will admit that I have very little rationale to back this premise up - it's more of a personal practice.

Re: [go-nuts] Define method on scope-local type

It would probably be useful, but to be fair, I rarely had this problem aside from sort. I think this mechanism is better suited for the occasional edge-case (as it doesn't require a language change): https://github.com/golang/go/issues/4146 On Fri, Aug 19, 2016 at 8:49 PM, Joshua Liebow-Feeser

Re: [go-nuts] Define method on scope-local type

Does it really make sense to create an internal package just to define a single small, one-off type? Also, I don't imagine that any of the optimizations would need to be reconsidered; the scope is strictly a subset of the scope at which the optimizations operated before, so there shouldn't be any

Re: [go-nuts] Define method on scope-local type

I did indeed mean to reply to all (done that this time)! Sure, I understand that it's "cleaner", but I'm advocating the internal package approach because: - it solves the problem today - it benefits from being able to take advantage of existing compile time optimisations without needing

Re: [go-nuts] Define method on scope-local type

Hey Paul, I think those are interesting ideas, but my concern about scope-local methods extends beyond just the methods of the sort.Interface interface; I was just using that as an example. The same complaint applies for any type used only within a given scope that needs to implement any

Hi Paraiso, I just did some research about database access and found this reddit link  https://www.reddit.com/r/golang/comments/2t52u7/how_do_you_write_functions_that_access_database/ I thought, there might be some well known pattern to access database and widely popular in go community.

[go-nuts] Re: Database design pattern

I find your question strange because, unless you have a specific architectural problem , which you don't, AFAIK, you shouldn't try to force patterns in your code. Write code that is testable then refactor if needed. Don't try to force a specific pattern just because "patterns". Now if you are
