See code below, there are two mutating accesses that should be error and are
not:
class X {
private static int globalData;
void breaksPure() pure const
{
//globalData++; // SHOULD BE ERROR
//X.globalData++; // SHOULD BE ERROR
this.globalData++; // SHOULD BE ERROR
int a = this.globalData; // But readonly access is ok!
}
}
static void breaksPure2(X x) pure {
x.globalData++; // SHOULD BE ERROR
int a = x.globalData; // But readonly access is ok!
}
