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.)
