This doesn't forbid assigning them to block properties... is that intentional?
typedef void (^Block)(int);
@interface Foo
@property Block B;
@end
void foo(Foo *f, Block __attribute__((noescape)) b) {
f.B = b;
}
================
Comment at: include/clang/Basic/AttrDocs.td:123
+* Cannot be captured by a block
+* Cannot be assigned to a variable
+
----------------
Is it helpful to forbid taking the address of them, too?
