Forgot to include the optional leading |this| parameter, so the above two production-sets should be:

ArrowFunctionExpression :
    ArrowFormalParametersOpt Arrow [lookahead ∉ {{}] InitialExpression
    ArrowFormalParametersOpt Arrow Block

ArrowFormalParameters :
    ( FormalParameterListOpt )
    ( this InitialiserOpt )
    ( this InitialiserOpt , FormalParameterList )

("Opt" at the end is because I can't get dokuwiki to do a subscripted "opt" as ES1-5's grammars do for optional right-hand side terms -- at least not without a dokuwiki plugin.)
