[racket] Shared and structs with #:auto

>From the struct docs:
constructor-id (which defaults to id), a constructor procedure that takes m arguments and returns a new instance of the structure type, where m is the number of fields that do not include an #:auto option.

You don't give anything to the constructor for #:auto fields.

Subject: [racket] Shared and structs with #:auto



Hi all, 

I'm trying to use shared with a structure that has a field with #:auto 

If I have some structure like this: 


(struct test ([a #:auto]) #:transparent #:mutable) 



this works fine: 


(shared ([b (test)]) b) 


but this errors: 


(shared ([b (test 1)]) b) 

with "shared: wrong argument count for structure constructor; expected 0, found 1 in: (test1 1)" 


Is this a bug? Is there a work around?
