Haskell Module

All we actually declare here is the top-level structure for a module.

Constructors

HsModule
AnnKeywordIds
- AnnModule,AnnWhere
- AnnOpen,AnnSemi, AnnClose for explicit braces and semi around hsmodImports,hsmodDecls if this style is used.
- hsmodExt :: XCModule p
  HsModule extension point
- hsmodName :: Maybe (XRec p ModuleName)
  Nothing: "module X where" is omitted (in which case the next field is Nothing too)
- hsmodExports :: Maybe (XRec p [LIE p])
  Export list
  - Nothing: export list omitted, so export everything
  - Just []: export nothing
  - Just [...]: as you would expect...
  - AnnKeywordIds : AnnOpen ,AnnClose
- hsmodImports :: [LImportDecl p]
- hsmodDecls :: [LHsDecl p]
  Type, class, value, and interface signature decls
XModule !(XXModule p)
