I don't think it is very hard:
MemberExpression :
MemberExpression . ( CascadeList )
...
CascadeList :
Cascade
CascadeList ; Cascade
Cascade :
PropertyName = AssignmentExpression
PropertyName Arguments
PropertyName .( CascadeList )
where all the non-terminals not explicitly specified above have there current
(future) ES5/6 definitions. In particular:
PropertyName :
IdentifierName
StringLiteral
NumericLiteral
@ Identifier //a hypothetical new addition for private name
I don't yet love using parens in this way, but it seems that it could work for
all of these cascade forms
