This is a great point José i. e. reading code vs. writing code. When I'm writing code I never expect ' to behave the same as ". I guess it's just years of software development that have conditioned me to be surprised if they're interchangeable in a language.
But when reading code it can be easy to conflate one with the other because there's not a lot of psychological distance between ' and " (and heaven help us with languages that use ` as well). So I think from the standpoint of making the code less error-prone under maintenance there's a good argument to be made for forcing people to use ~c. It will make the distinction more obvious for those reading the code later on. Things like this and slashed zeros in programming fonts are small things but they can make a lot of difference to maintenance developers. oc On Thursday, September 22, 2016 at 3:13:12 PM UTC-4, José Valim wrote: > > Single quotes will become a syntax error in Elixir 2.0. > > We need to consider two scenarios here: reading code and writing code. > > I believe that when someone reads ~c"" for the first time compared to '', > the sigil version will be more foreign, while the single quotes is more > likely to be assumed to be *something*.
