I generally refer to method definitions outside of a class definition,
as out-of-class definitions.
They can be inline or not, so I find it less than clear to refer to them
as sort of the opposite of inline (namely “out-of-line”).
I wouldn't offhand understand “deported”. Now that you've mentioned it I
may remember it. Or not. ;-)
