> There's also `Kernel.match?/2`, which is awkward to use [...] It's neither more complex to write nor understand than `if_match`. I would argue it just seems awkward because you haven't used it a lot? -- At least it felt awkward to me the first few times I used it.
Assuming we ruled out `if_match`, the only alternative would be `<-`, custom use case of `=` or a similar solution. Personally, I hate it when languages start using what feels like millions of "nice", "short", "clear" syntax trickeries for any given [edge] case. It's just extremely hard to read in other people's code if you're not that experienced and a hassle to remember for yourselves, if you don't use it a lot. I know I'm often times a bit of a buzzkill when it comes to little additions/changes like this but I feel the currently available solutions suffice. -sven On Fri, 18 Oct 2019 at 02:03, José Valim <jose.va...@plataformatec.com.br> wrote: > > But I see your point: it is not and it was never the intention for it > to be. > > Exactly.
