The purpose of this patch, as @wangpc states, is to capture the ability to concatenate code strings. IMO we should go with the simplest and most straightforward approach. Maybe we should prefer lambdas/functions over format since the semantics for format is a particularly complex and non-standard one when we look at different languages (i.e. escaping, named args, positional args, formatters), while lambdas and functions are relatively more universal.
