I'd find it fantastic if they added
var list: String... = 1, 2,3,4,5
However if they remove Variadic arguments then apple would need to remove
it from their apis. To name a few...
Removing variadic arguments would be a breaking change though. They would
either need to remove it quickly or deprecate all the methods that use
variadic arguments. Might take awhile before it is removed completely.
