[swift-evolution] Proposal: Introduce User-defined "Dynamic Member Lookup" Types

[Benjamin Garrigues]

There are fields where there is no swift culture at all, or barely none, for example on the server side. I don’t want to see « swift-django » winning this battle. I like compile-type safety, because i know that in the long term it makes my code more manageable. But in some cases it’s hard to promote long term over short term. It’s hard to tell someone in your team « yes, you should take the time to define that struct for parsing your JSON api , even if you’ve got tight delay, rather than rely on dynamiclookup ».

Best practices don’t magically conquer a community, they do so because senior devs start banning the dangerous ones and because the language or compiler warning help them to.

I mean, why not? They are not going to affect my code or the libraries I use. Why not let them exist? What's with the elitism?
