* [SR-11298][]:
30+
31+
A class-constrained protocol extension, where the extended protocol does
32+
not impose a class constraint, will now infer the constraint implicitly.
33+
34+
```swift
35+
protocol Foo {}
36+
class Bar: Foo {
37+
var someProperty: Int = 0
38+
}
39+
40+
// Even though 'Foo' does not impose a class constraint, it is automatically
41+
// inferred due to the Self: Bar constraint.
42+
extension Foo where Self: Bar {
43+
var anotherProperty: Int {
44+
get { return someProperty }
45+
// As a result, the setter is now implicitly nonmutating, just like it would
46+
// be if 'Foo' had a class constraint.
47+
set { someProperty = newValue }
48+
}
49+
}
50+
```
51+
52+
As a result, this could lead to code that currently compiles today to throw an error.
53+
54+
```swift
55+
protocol Foo {
56+
var someProperty: Int { get set }
57+
}
58+
59+
class Bar: Foo {
60+
var someProperty = 0
61+
}
62+
63+
extension Foo where Self: Bar {
64+
var anotherProperty1: Int {
65+
get { return someProperty }
66+
// This will now error, because the protocol requirement
67+
// is implicitly mutating and the setter is implicitly
68+
// nonmutating.
69+
set { someProperty = newValue } // Error
70+
}
71+
}
72+
```
73+
74+
**Workaround**: Define a new mutable variable inside the setter that has a reference to `self`:
75+
76+
```swift
77+
var anotherProperty1: Int {
78+
get { return someProperty }
79+
set {
80+
var mutableSelf = self
81+
mutableSelf.someProperty = newValue // Okay
82+
}
83+
}
84+
```
