1.  case class Apply(fun: Tree, args: List[Tree])(implicit pos: Position) extends Tree with Product with Serializable

   Syntactic apply.

   Syntactic apply. It is a method call if fun is a dot-select or bracket-select. It is a function call otherwise.

19.  case class Export(bindings: List[(Ident, ExportName)])(implicit pos: Position) extends Tree with Product with Serializable

    export statement.

    export statement.

    This corresponds to the following syntax:

    export { <binding1_1> as <binding1_2>, ..., <bindingN_1> as <bindingN_2> }

    The _1 parts of bindings are therefore the identifiers from the current module that are exported. The _2 parts are the names under which they are exported to other modules.

20.  case class ExportName(name: String)(implicit pos: Position) extends Product with Serializable

    The name of an ES module export.

    The name of an ES module export.

    It must be a valid IdentifierName, as tested by ExportName.isValidExportName.

21.  case class For(init: Tree, guard: Tree, update: Tree, body: Tree)(implicit pos: Position) extends Tree with Product with Serializable
22.  case class ForIn(lhs: Tree, obj: Tree, body: Tree)(implicit pos: Position) extends Tree with Product with Serializable

25.  case class GetterDef(static: Boolean, name: PropertyName, body: Tree)(implicit pos: Position) extends Tree with Product with Serializable
26.  case class Ident(name: String, originalName: Option[String])(implicit pos: Position) extends PropertyName with Product with Serializable

28.  case class Import(bindings: List[(ExportName, Ident)], from: StringLiteral)(implicit pos: Position) extends Tree with Product with Serializable

    import statement, except namespace import.

    import statement, except namespace import.

    This corresponds to the following syntax:

    import { <binding1_1> as <binding1_2>, ..., <bindingN_1> as <bindingN_2> } from <from>

    The _1 parts of bindings are therefore the identifier names that are imported, as specified in export clauses of the module. The _2 parts are the names under which they are imported in the current module.

    Special cases:

    • When _1.name == _2.name, there is shorter syntax in ES, i.e., import { binding } from 'from'.
    • When _1.name == "default", it is equivalent to a default import.
29.  case class ImportNamespace(binding: Ident, from: StringLiteral)(implicit pos: Position) extends Tree with Product with Serializable

    Namespace import statement.

    Namespace import statement.

    This corresponds to the following syntax:

    import * as <binding> from <from>
