I know it's frustrating to convert one piece of software based on a set of idioms, to another language that uses other idioms. I can remember trying to convert some highly OO JavaScript code to Delphi -- oh it was a pain and in the end it looked terrible in Delphi. I guess one point everyone is trying to get across is that "Go doesn't have a multidimensional array -- at least not a convenient one -- for a reason." Implicit structures significantly harm readability at the cost of convenience. I.e. it's probably fine for small code bases (i.e. below 50KLOC and ~5 people), but the larger it gets the harder it is to verify that the structures are consistently used. This means that refactoring is more difficult. *(You can partly see TypeScript and Hack as trying to deal with the aftermath.)* But, I should say -- I love JS objects -- they are super-convenient and nice to use... but I wouldn't use them in Go. So, let's take a step back, and investigate how people would solve your problem in Go -- rather than figuring out, how to write PHP code in Go. Remember Go is not PHP, JS nor Haskell... hence the code you write in Go will look different than in any of those languages. Yes, the larger code structures will stay the same, but the details will vary. *Sure, the first conversion could be crude.* Basically, what business problem are you trying to solve with multidimensional arrays? If you can show the PHP code you are trying to convert, it would be even better. + Egon -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
