Re: Named arguments in C

It really needs language support. That has been done in C for
designated initialisers; named args are a similar feature, easier to
implement (they can only be one level deep for example) and IMO far
more useful.

Although there are a few extra problems with C because the extra info
needed (parameter names and default values) can appear in both the
definition, and any number of prototype declarations, which cannot in
conflict.

As I recall, we had this discussion here a while ago.  The fact that C
allows parameter names for a function definition to differ from those in
corresponding declarations is a bit inconvenient.  But what I recall
suggesting at the time is that the parameter names in a call need to be
consistent with the names in the visible declaration.

    void foo(int x, int y) {
        // ...
    }

    void foo(int xx, int yy);

    foo(xx: 10, yy: 20);
