the result of the getter will be read-only
My intention is not to have a read-only getter, I want to call
SomeProp on a const object:
class S
{
private int cache = -1;
private int SomeExpensiveOp() { return 12345; }
public @property const(int) SomeProp()
{
if (cache = -1)
cache = SomeExpensiveOp();
return cache;
}
}
unittest
{
const(S) s = new S();
auto i = s.SomeProp; //mutable method S.SomeProp is not
callable using a const object
}
right, i have not carefully read the body of the Q. my bad.
