[racket] Are there any functional structs in Racket

I have a prototype that supports syntax like this one: 

 (dot a-world ufo wings left)

which would select the left field of a wings field in a ufo field of a world struct. 


 (set a-world ufo wings left 'broken)

would be a functional update. 

I intend to add it into the 2htdp languages.
