999. “Implicit” or “implied” object argument/parameter?

[Voted into WP at March, 2010 meeting.]

The terminology used to refer to the parameter forthis and its corresponding argument is inconsistent,sometimes using “implied” and sometimes“implicit.” It would be easier to search the text ofthe Standard if this usage were made regular.

Proposed resolution (February, 2010):

1. Change the index to refer to“implicit object parameter” and “implied objectargument” instead of the current permutations of theseterms.

2. Change 12.2 [over.match] paragraph 1 as follows:

...how well (for non-static member functions) the object matchestheimpliedimplicit object parameter...

3. Change 12.2.2 [over.match.funcs] paragraph 4 as follows:

...For conversion functions, the function is considered to be amember of the class of theimplicitimpliedobject argument for the purpose of defining the type of theimplicit object parameter...

4. Change the footnote in 12.2.4 [over.match.best]bullet 1.1 as follows:

• [Footnote: If a function is a static memberfunction, this definition means that the first argument, theimplied objectparameterargument, has noeffect in the determination of whether the function is better orworse than any other function. —endfootnote]
