Ambas bigStepSemantics e smallStepSemantics, importadas em testBigStep, contém uma metafunção ⊕
Em bigStepSemantics:
(define-metafunction PegRelation ⊕ : t t -> t [(⊕ (boolean_1 hs_1) (boolean_2 hs_2)) (,(or (term boolean_1) (term boolean_2)) (∪ hs_1 hs_2))])
Em smallStepSemantics:
(define-metafunction Reduct [(⊕ natural_1 natural_2) ,(+ (term natural_1) (term natural_2))] )
O que resulta no erro:
testBigStep.rkt:9:9: module: identifier already required at: ⊕ in: "../smallStepSemantics.rkt" also provided by: "../bigStepSemantics.rkt" #(156 27)
