PureScript 0.7.5 发布，主要更新如下： 改进 Pretty printing of types and expressions in errors was improved (@paf31) Externs files are now saved as JSON (@paf31) Support for parallel builds has been added (@paf31) Builds will now use multiple cores by default, but the number of capabilities can be modified by passing the -N option to the GHC runtime: psc <input files> +RTS -N8 Binders can now be given type annotations (@5outh) For example: example = do n :: Int <- get put (n + 1) This can be useful when disambiguating types. There is a new warning for missing type signatures on top-level declarations (@paf31) There are new warnings for shadowed and unused type variables (@garyb) Contextual information in warnings was improved (@garyb) The qualified keyword is now optional when importing modules qualified (@michaelficarra) @zudov changed the behavior of PSCi on CTRL+C/D to match GHCi and other REPLs. A bug in row unification was fixed (#1310, @paf31) Constrained types can now be defined without a forall keyword. This is useful in some nullary type class and rank-N scenarios. (@paf31) Bug 修复 @garyb added some additional checks for transitive module exports. Type synonyms are now expanded more eagerly to avoid some error cases in the type checker (@paf31) Better support for multi-byte UTF-8 characters (@senju) A check has been added to the exhaustivity checker to avoid exponential blowup (@paf31) Empty case statements are no longer syntactically valid (@zudov) 其它 @aspidites fixed all compiler warnings in the core libraries. @zudov and @phadej have made improvements to the Stack distribution of the compiler, and the Stackage builds. @garyb has added a warning for operators in type classes, since they will be disallowed before 0.8. 更多内容及下载页面：v0.7.5 PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。purescript 主要是由 Haskell 和 PureScript 编写的。 PureScript 0.7.5 发布，静态类型语言下载地址
