[swift-evolution] Potential problamatic initializers, solved by removing tuple splat?

let tenXs = String(count: 10, repeatedValue: Character("X"))
let tenYs = String(count: 10, repaetedValue: Character("Y"))
print(tenXs) // Prints XXXXXXXXXX
print(tenYs) // Prints (10, "Y")
So, why doesn't tenYs print the expected YYYYYYYYYY?
- Because of the slightly misspelled repeatedValues parameter label.
Then why no compile time error for the misspelled parameter label?
- Because of this String intializer: public init<T>(_ instance: T)
I guess there are other similar examples, but I happened to stumble upon
this one just now.
Should they be considered a problem?
Is this an example of a problem that will be solved by removing tuple splat?
