 By default, Racket code cannot reference names bound with DSL @tech{binding classes}. To allow such references, specify a @deftech{reference compiler} for each class of bindings that should be usable in Racket code. The reference compiler is a @tech/reference{syntax transformer} that will be applied to compile the syntax including each reference.
