They can, see my prev post.

It's less readable, less maintainable, more obscure to those reading the
code... the language had an awesome feature that addressed it directly.
When mixins get involved, readability, syntax highlighting, and other basic
IDE services all go out the window.

Perhaps the most important one that I forgot; debugging becomes VERY
annoying. Try stepping into an engine API when it's wrapped up with
magic... F10 (jumps to a rubbish API file, cursor disappears, stub code
doesn't actually exist). Continue pressing F10 for a while until it
eventually finds it's way into the function pointer. Repeat when leaving
the function >_< .. Again, __forceinline would address this.

I understand that you've probably got so many of these, it's drudgery to

It would be annoying.

Question: are the default values all of the form T.init? I.e. is

No, I don't think so. Color inits to black. Many enums also have an Unknown
state. and float init's to NaN for some crazy reason ;)
