I think what the docs mean is that as soon as an anonymous union is

I understood that, hence my remark that "this is not helpful".
OK. I thought you meant that the documentation is not helpful enough to
understand what it means.
So it seems I am forced to assign explicitly to each member of the
struct, an ugly process.
What is a nice way to solve this problem?
I think the only way to solve it is with a constructor:
this(int ival, double xval) { i = ival; x = xval; }
As I though I made clear, I don't want write assignments to each
variable in a 50 or 100 member struct from a library when D could supply
a better solution.
Sorry, I thought you meant to assign the fields manually outside an
initializer function.
I can print out such a struct using writeln, but can
find no way to use that text cleaned up in source code to create such a
struct. Is D completely deficient here?
Hm... have you tried named field initializers?
mess m = { i: 99, x: 3.14};
Seems to work for me.
I believe you could generate a constructor given the introspection of
the fields themselves. Probably would be messy though.
