[swift-evolution] Analysis of case conventions for initialisms

[Carlos Parada]

I’ve used the .NET frameworks and conventions extensibly and while some of them didn’t look quite right initially, they grew up on me and now I prefer them.

They do seem to use uppercase for two letter acronyms, but not for abbreviations though. When I started doing .NET I was so used to typing ID (as in identifier), but their convention is to type Id, as in CustomerId, or idForObject. It makes sense, just as you would use Ptr for Pointer, or Int for Integer.
