clear as a global function is for destroying a class/struct
clear as a member can do anything. clear is not a keyword.
clear(container) -> same as delete container, but without freeing any
memory.
container.clear() -> remove all elements
This has been brought up before as a problem, I'm not sure it's that
terrible, but I can see why there might be confusion.
Thanks for the example, this semantical issue was bugging me for a while
(not the OOP vs whatever flamewar).
Is there a semantical difference between "function(obj)" and
"obj.function()"?
If we are not clear on this simple thing, we should just stop here :)
