e.g. local = bar, imported = Some(foo) for import { foo as bar } from 'mod.js' ImportStarAsSpecifier e.g. import * as foo from 'mod.js'. ImportWith According to the current spec with of crate::ImportDecl can only have
strings or idents as keys, can’t be nested, can only have string literals as
values: ImportWithItem Invalid Represents a invalid node.

export =. But for @babel/parser, export default is an ExportDefaultDecl,
so a TsExportAssignment is always export =.
