Is 'equals' a function on this interface?
No, it's a new global function in object.di, and it's called opEquals, not
equals. I guess I messed that up royally :)
Just do me == they;
That will call the function.
But it still calls Object.opEquals:
Error: function object.opEquals (Object lhs, Object rhs) is not callable
using argument types (I,I)
This is not Object.opEquals, it's object.opEquals -- note the
capitalization. The latter is a standalone function in module object.
Error: cannot implicitly convert expression (i) of type deneme.I to
object.Object
Error: cannot implicitly convert expression (i) of type deneme.I to
object.Object
This is a bug. i == i should call the opEquals method on i. Instead, the
compiler is trying to call the standalone opEquals(Object, Object)
function.
I confirmed with 2.043 that this is a bug. I'll file with a test case.
