well... I do have to. I get "can't determine which overloaded function to call"
because I have a lot of similar-looking functions and := operators
You're right, I verified it just now. I didn't remembered it correctly.
FYI, bellow is the verification example used, later modified to
compile successfully with trunk FPC. Introduction of the ':='
operators for T1 and T2 enabled the '+' operator commutativity.
Can I have a reality check on this please: in this context is the
overloaded := effectively an implicit cast as well as an explicit operator?
Is the availability of overloaded + and := operators necessary and
sufficient for += to work correctly?
