[plt-dev] infix prefab literals

[Dave Herman]

Would it cause any problems to extend the reader syntax of prefab 
literals to allow the double-dotted-infix notation? E.g.:

     > (define-struct : (name binding) #:prefab)
     > #s(foo . : . 42)
     #s(: foo 42)
     > (equal? #s(foo . : . 42) #s(: foo 42))
     #t
