Static Semantics: Early Errors
Module : ModuleBody
It is a Syntax Error if AllPrivateNamesValid of ModuleBody with an empty List as an argument is false.
Static Semantics: AllPrivateNamesValid
AllPrivateNamesValid is an abstract operation which takes names as an argument.
MemberExpression : MemberExpression . PrivateName
1. If StringValue of PrivateName is in names, return true.
2. Return false.
CallExpression : CallExpression . PrivateName
1. If StringValue of PrivateName is in names, return true.
2. Return false.
ClassBody:ClassElementList
1. Let newNames be the concatenation of names with PrivateBoundNames of ClassBody.
2.Return AllPrivateNamesValid of ClassElementList with the argument newNames.
For all other grammatical productions, recurse on subexpressions/substatements, passing in the names of the caller. If all pieces return true, then return true. If any returns false, return false.
