where does this belong?

[prj@po.cwru.edu (Paul Jarc)]

I came up with a meta-macro called nnmaildir--defstruct for defining
data structures.  Sample use:

(nnmaildir--defstruct nnmaildir--srv
  [address    ;; the server address string
   method     ;; the select method
   ...
   ])

This defines macros such as nnmaildir--srv-get-address and
nnmaildir--srv-set-address which expand to aref and aset forms, much
like the gnus-info-* macros, complete with automatic docstrings.  This
makes for less typing and prevents me from accidentally using a
different index in the -get- and -set- macros for the same member of a
data structure.

After I wrote this, I realized its usefulness really isn't limited to
nnmaildir.  E.g., the gnus-info-* macros could maybe be reimplemented
with this.  So where would be a good place for it?  gnus-util.el?
gnus.el?
