PureScript 0.8.0 rc1 发布，静态类型语言
欢迎加入运维网交流群:263444886PureScript 0.8.0 rc1 发布，更新如下：
重大变更
None, but there are lots of new warnings related to upcoming breaking changes in 0.9:
[*] Operators as aliases will become mandatory, and regular operators (as functions) will now generate warnings.
[*] Non-exhaustive functions will get a Partial constraint in 0.9, so the exhaustivity checker will now attempt to generate warnings by looking for Partial constraints in scope.
[*] The qualified import syntax has been deprecated.
[*] Class imports will use the new class syntax in 0.9 and the alternative syntax is deprecated.
