Hi all,
I'm in the process of implementing SE-0035, which limits capturing inout
parameter to @noescape contexts. The proposal is clear on capture behavior for
the following:
1. closure literals
2. nested function passed as arguments.
But I'm not sure what to do with this case, in which 'x' escapes.
func captureAndEscape(inout x: Int) -> () -> Void { func foo()
{ _ = x } return foo }
The most obvious answer is it should be considered with the same rule as
a closure literal, but a nested function can not have @noescape in its type
(for now anyways).
So, should this be legal, then? If not, where/how should the error be?
