    [parser] Improve error when using import decl in a script · e101b9c0
    Sathya Gunasekaran authored
    Perform a best-effort check for module context and provide an
    appropriate error.
    
    As seen from the import-blah-script.js test, we could have invalid
    import expressions in a script context that could result in an error
    saying "Cannot use import statement outside a module" which isn't
    the ideal error because the error is an incorrect import
    expression.
    
    But, when the developer changes to a module context, the
    correct error is thrown.
    
    To fix this, we'd have to refactor and call ParseImportDeclaration,
    and then throw an appropriate error, which seems like a lot of
    overhead for not enough gain.
