If you want the API to choose the formatter, you can take it as parameter like
a normal lambda
formatter -> formatter."Hello \{name()}"
You do not need to provide an access to a TemplateString explicitly in the
language because you can have a TemplatePolicy identity that returns the one
taken as argument.

I don't understand, those expressions, lambdas and method references already
exist in Java.
