What I would love would be being able to pass an anonymous struct 
to a template. Then you can reflect over it to get declarations 
and group them too.

(Actually, I'd love to be able to use anonymous structs anywhere 
a typename is expected. Then you could do:

struct { int a; } foo; // declare a variable named foo as type 
struct { int a; }

but that might break the parser.)
