* Accessing `ta[0]` throws a TypeError. * Fix array indices starting at 0 and property references * Fix classfields templates for properly checking static propnames. * Generate tests * `assert.equal` is not defined * Add missing includes * Generate tests * typo s/Avalue/42/ * fix whitespace * Add missing var for strict mode * Expand generated class fields tests for forbidden computed property name values Ref https://github.com/tc39/test262/pull/1339#issuecomment-342830243 * derived classes have access to private names in base classes, if private names are in scope
