我可以使用:l addOne.hs
如果我加载另一个haskell文件:l addTwo.hs，它将擦除对另一个文件的引用，并且在尝试调用Variable not in scope: addOne时出现addOne错误
addOne.hs
addOne x = x + 1
addTwo.hs
addTwo x = x + 2
还有其他几篇关于加载多个模块的文章。是达到上述要求的唯一方法，将它们转换为模块并调用
> :load Module1 Module2
> :module Module1 Module2

仅包含模块主体的模块的缩写形式是允许的。如果使用此选项，则假定标题为
res.data。
我认为您不能在{
"items":[
{
"ibn":123,
"name":"Harry Potter",
"author":"J K Rowling",
"genre":"fantasy",
"publisher":"bloomsbury",
"ebook":"yes",
"audiobook":"yes",

"price":"500"
},

}
]
}
中装入两个名称相同的模块（模块的真实名称；您可以使用别名合格的导入）。
