C Macro Reflection in Zig – Zig Has Better C Interop Than C Itself

I mean, there can always be a function on the TranslateC step which maps 'special case' names (or even translate them to an entirely different name, for instance when there's collisions with Zig reserved keywords):

    translateSpecialCaseNames(.{
        .{ .src = "ABOMINATIONCase", .dst = "case" },
        .{ .src = "NAMESPACED_PascalCase", .dst = "pascalCase" },
    });

...in my own language bindings generator, being able to define such special case mappings is actually quite important, mainly for handling that situation where an automatic mapping would result in a reserved keyword.

Reserved words really shouldn't require manual care; "list of keywords in X language" is really easy to handle so you can just append an underscore.

I do think that namespaces need to be semi-manually managed though (likely only at the project level), since often there are things that look like a namespace but shouldn't be treated like one, and it's not always obvious from a single identifier how many words should be treated as the namespace in some styles.

One special case is that sometimes C-ish libraries have class-likes like {Foo, FooBar, FooBaz} where the desired mapping is {foo.Foo, foo.Bar, foo.Baz}.
