Video: Using Gleam's 'try' syntax by Michael Jones

Michael published this video today on the how and why of Gleam’s new try syntax. I thought it would be a good first bit of content to share here on devtalk.

I hope he makes more Gleam educational snippets in future!

I liked this, and your Elm video too!

One other thing that might confuse people about the try syntax is what to do if your results have different error types. If you are looking for ideas for videos, maybe a follow-up about how to use map_error would be useful too.

I reckon Michael should sign up gleam[casts].com! He’s got a good voice and everything was at a relaxed pace which is ideal for screencasts imo :+1: (I don’t think he’s signed up yet otherwise I would have @'d him, haha!)

At the moment the plan is to only have this Result specialisation. Later we may introduce traits, interfaces, or some other form of metaprogramming/ad-hoc polymorphism, at which point we could look at expanding this.
