I too find this very useful. I am also having this situation
often when
there is an array of nested struct instances inside a class
environment.
This is a common scenario and deserves attention. Also I
believe (looking
at D1 forums) that there was a time in the past when D1 nested
structs did
support 'outer'.
But unfortunately structs are neglected part of D, so I am not
sure if
developers give an ear to this thread. To make D truly a
systems language
we need to make structs more robust and feature rich.

If I want to manually pass the parent pointer to a child struct,
how do I do it? The compiler won't allow me to use "this" from
the parent until after the parent has been instantiated.
The solution I came up with is to create a default constructor
for the parent that sets the child struct with the parents
pointer. It works but maybe there's a better way?
BTW, the same situation happens with structs defined inside
structs, they will not have access to the parent struct members
unless you manually pass a pointer into the child struct at some
point after the parent struct's address becomes known. You cannot
create a default constructor for a struct, so reliably
initializing the child struct with the parents pointer is
problematic.
