With nested structs, however, you can't do much. You can pass them
to a template, but I can't see some solid use cases there. My
understanding is that nested structs have been implemented for
completeness and consistency with nested classes.
Any good example of nested struct uses?
I have used nested static structs sometimes, when I need a struct
just inside a function (like the main()) to avoid polluting the outer
scope with the struct name.
Do you want to remove them from D2?

I've had similar uses, some win32 api routines require custom structs
like BITMAPINFO, nested structs are neat to declare the struct right
before its only usage.
However I don't think having a closure for that struct is really
needed, nested functions already perform that task very well, and I
use those quite often.

I use structs in nested functions as context for parallel recursive
loops, actually my code would be nicer if circular referring structs
would be allowed in nested functions (at the moment this is not
possible, even with forward references).

Could you prepend "static" in front of their definition and still have
them work?
