Bikeshedding: Is it grammatically possible (or even desirable) to skip the
“any” token and just have something like this:
var view: <UIView, SomeProtocol>
init(view: <UIView, SomeProtocol>) {}
if let mergedValue = button as? <UIView, SomeProtocol> {}
let a: <UIScrollView, <UITableView, any<UIView, ProtocolA>>>
I’m not even sure there’s a huge advantage to leaving it out (avoid capturing a
new keyword?) - just thought I’d ask!
And while I’m here asking about (likely very silly) things, I wanted to note
that the < and > symbols are heavily ingrained as generics to me and this seems
like.. not really the same kind of thing? Has the potential for confusion about
this been considered at all? It’s almost like what is being expressed is,
“here’s a set/collection of requirements” and, in that case, it almost seems
like it should look more like an array:
var view: [UIView, SomeProtocol]
init(view: [UIView, SomeProtocol]) {}
if let mergedValue = button as? [UIView, SomeProtocol] {}
let a: [UIScrollView, [UITableView, [UIView, ProtocolA]]]
Would that lead to a better syntax if such things as generic protocols were
possible (assuming they are even desirable)? Example:
let a: [UIView, MyProtocol<Int>]

Sean - who might just be confused about things due to a lack of attention
spa... ooh shiny things!
