/** Normally, a property cannot be both 'readonly' and having a "write" attribute
|
|
(copy/retain/etc.). But, property declaration in primary class and protcols
|
|
are tentative as they may be overridden into a 'readwrite' property in class
|
|
extensions. Postpone diagnosing such warnings until the class implementation
|
|
is seen.
