    [parser] Fix escaped contextual keyword handling · a94c91ca
    Toon Verwaest authored
    Escaped contextual keywords are simply valid identifiers if they do not occur
    in the context where they are a keyword. Escape sequences of the form \uNNNN
    or \u{NNNNNN} must be consumed as part of the identifier.
    
    If such escaped contextual keywords do occur in a context where they are a
    keyword, they are a syntax error. In that case we manually check locally
    whether they are escaped.
