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 alw

In computer programming, remove means to remove some elements out of many elements. So, here you assume, there are many files in a container and when you you remove a file, one file disappears and others remain. The whole container remains the same. delete/erase means to wipe out something comp

Re: [go-nuts] Unary +

x would already be signed during implicit type inference. The inferred type is either the one specified in an argument or declaration, or it's the default type (which is int, thus signed). I don't know the answer to your question though. I didn't even know this existed… On Fri, Aug 19, 2016 at 9:

What is the purpose of the unary '+' operator? In both C and Go they are syntactically correct but neither generate instructions to modify the expression. The '-' operator obviously generates a neg or sub from 0 instruction to negate the result by inverting the expression with an add with carr

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

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 interf
