Another option would be to add an

if (is_eval_scope()) return true;

to Scope::MustAllocateInContext(). I think that would be a little more
idiomatic, though there's likely room for some cleanup here...

-      !is_function_scope() && outer_scope->has_forced_context_allocation();
+      (!is_function_scope() && outer_scope->has_forced_context_allocation()) ||
+      is_eval_scope();
   outer_scope_->AddInnerScope(this);
 }
