mixin(cvars!
`
    int window.width as width = 640;
    int window.height as height = 480;
`
);

and

mixin(cvars!
(
    int, "window.width, width", 640,
    int, "window.height, height", 480
)
);

are functionally the same, and have almost exactly the same length.

Except the first looks cooler and has a more natural syntax.  Sometimes,
that's important.

As for the IDE issue, I'm increasingly of the opinion that this is a
shortcoming of IDEs.  For example, I've never seen an IDE that got
script in HTML right.  Certainly not if you change the language being
used under it's feet.

Maybe it's time IDEs started supporting embedded DSLs as a matter of
course.  Dunno how, but that's their problem, not mine.  :P
