IMO nice idea, but I see that this could be confused with using enum values:
enum E {
case one
case two
static func foo(e: E) {}
}
struct S {
var one = 100
...
func f() {
E.foo(.one)
print(one) // ? print(.one)
someFunc(.something) // is it enum or property of this struct S?
}
}
Probably another variants like `:` symbol could be suggested:
func f() {
E.foo(.one)
print(:one)
someFunc(:something)
}
But also not ideal.
But all this just a discussions - there was clear opinion of core team
posted that Swift should not have requirement to explicitly decorate type
properties inside code (explicit `self.` or similar). So, someone who wants
to use explicit 'self.' - can use it. Others - will not use.

Since this keeps coming up, it seems that something would be good here.
Perhaps this has been explored before but why can’t we just use dot without
the word “self", to indicate self?
classDotIsSelf
{
funcp() -> String{
return"self p"
}
funcg() {
print(.p()) // print “self p"
print(p)// error undefined
letp = "local p"
print(p) // print “local p"
print(.p())// print “self p”
}
classfunck() -> String
{
return "self k"
}
classfuncj() {
print(.k()) // print “self k"
print(k)// error undefined
letk = "local k”
print(k) // print “local k"
print(.k()) // print “self k"
}
}
Self could still be used but “self.” or “.” would be required to access self.
Rationale:
• since self is referenced quite often in classes it should be very short
and easy to type
• less cluttered than self being everywhere but not ambiguous. whether you
mean the local variable or the instance.
* Already very similar notation for enums where you leave off the entity
name when it can be implied.
• Does not interfere, that I could see, with other uses of dot. (I am sure
I will be corrected if wrong, but putting it out there because I want to
know why :-)
• Feels quite intuitive and easy to understand.
* Make Swift safer because it eliminates potential ambiguity as has been
pointed out many times.
• Other characters would be less natural than dot.
• In the IDE, hitting dot would immediately bring up self items as choices.
