operator-overload ^ functions - incomplete summary

(IV? no)

Warning: some of the most important features/operations in c++ are implemented as special customizable operators like new/delete, qq(<<), call operator, OOC..., and their rules are sometimes unique, unusual and "bucking the trend". These help make OOL a rather confusing aspect of c++.

OOL has similar variations as function can have --
- free-standing OOL? Yes often as a friend function.
**Exception -- call operator must be a method though I'm not sure about static methods
**Exception -- I believe OOC must be a instance method.
- non-static non-virtual OOL? I think so. operators like ++ needs an instance.
- private non-static OOL? I think so
- (pure) virtual OOL? Probably not
- overloaded OOL? Yes esp assignment operator. I think qq/operator+/ too

Here's a major difference between OOL vs functions -
- Regular Functions have a return type, possibly void. In contrast, some OOL must return a type and some OOL must not. See other blog posts.
