Re: [go-nuts] Re: API patterns for a function with a single argument that is rarely needed

Yeah, that's my concern with creating an API which accepts a variadic number of arguments, but strongly encourages you to present at most one. Relying on documentation for thistriction is frankly, lame. Given the set of options, a second function for the uncommon invocation sounds like a reasonabl

Re: [go-nuts] Re: API patterns for a function with a single argument that is rarely needed

The variadic pattern is pretty good imo, but it does permit the caller to pass more than 1 value which implies you need to decide on the bahviour (first value wins, last value wins,etc ...), the document and add tests for the possible states. Iff there is only one possible option and it's only

Hey, so I've been running some benchmarks with a ticker in a one-second interval for about 30-40 minutes. For what I could see, it was running without much of a drift. Something tiny in the millisecond area which wouldn't be a problem. However, is there a possibility of a bigger shift occurring

Sam, Good naming is such a key part of a good API that the use of sterile names like Foo and Bar during design is doomed to failure. Perhaps it's like packages fmt and log: a default output and a user defined output. For example fmt.Print, fmt.Fprint. You have two functions. Peter On Friday,
