I find this a confusing reply. First, you seem to be confusing eager string interpolation with this lazy/deferred templating feature. I'm specifically asking about languages that have the latter. More confusingly, you bring up the language under discussion as an example... if it already had this feature, they wouldn't be adding a new feature. Then, you bring up 3rd party templating solutions, but this is off topic, as we are talking about language builtins. I am well aware there are many templating solutions to solve text templating in general. In summary, I'm specifically asking for examples of languages that allow string interpolation with _deferred/lazy_ processing, which is how I understand this feature. It seems there are a few, but it doesn't seem to be terribly common after reading the other comments.
