shouldn't this just be empty?
ExportAllDeclaration is specced to always have a source (eg it always exports from an external module and defines no local variables).
I know that visitExportDeclaration does if (node.source) { do nothing }, but why bother with the function call?
There was a problem hiding this comment.
Because I thought that people expect the method visitExportDeclaration to be called on all export declarations because of the name.

This PR fixes
eslint-scopeto support newexport * as foo from "source"syntax in ES2020.The syntax has added the
exportedproperty into theExportAllDeclarationnode foras foo. Thefooidentifier makes no references, soeslint-scopemust ignore theexportedproperty.In more general,
eslint-scopeshould ignore theExport(All|Default|Named)Declarationnodes if the node has theirsourceproperty (FromClause). Currentlyeslint-scopedoes so for onlyExportNamedDeclaration, therefore this PR addsExport(All|Default)Declaration, too.
