我在Coq中定义了一个定义了几个符号的模块签名。但是,当我尝试在签名之外使用这些符号时,Coq失败了。我的代码的简化版本如下。任何帮助将不胜感激。
Module Type Field_Axioms.
Delimit Scope Field_scope with F.
Open Scope Field_scope.
Parameter Element : Set.
Parameter addition : Element -> Element -> Element.
Infix " + " := addition : Field_scope. (* ASSIGNS THE "+" OPERATOR TO SCOPE. *)
End Field_Axioms
Module Type Ordered_Field_Axioms.
Declare Module Field : Field_Axioms.
Print Scope Field_scope. (* SHOWS THAT THE SCOPE IS EMPTY. *)
End Ordered_Field_Axioms.
答案 0 :(得分:2)
您可以替换:
Declare Module Field : Field_Axioms.
使用:
Declare Module Import Field : Field_Axioms.
