If case logical operator integration

Yeah, for what it's worth, using our case paths library your first situation can be expressed like so:

import CasePaths

@CasePathable
@dynamicMemberLookup
enum MyEnum {
	case first(data: String)
	case second(data: String)
	case third(data: [String])
	case fourth
	case fifth
	case sixth
}
let value1 = MyEnum.first(data: "Gabriel")
let value2 = MyEnum.second(data: "Aurora")
var value3 = MyEnum.third(data: ["Gabriel", "Aurora", "Marcela"])

if let data = value1.first ?? value2.second {
    print(data)
}

And your second situation like this:

if
  let data1 = value1.first,
  let data2 = value2.second,
  let data3 = value3.third
{
  print(data1)
  print(data2)
  print(data3)
}

And there are a few other niceties too, such as an expression version of case pattern matching:

if value1.is(\.first) {
  // ...
}

Of course, this is only viable if you are OK depending on a 3rd party library and OK with the cost of macros.
