String Tapas Redux: Beyond mere string interpolation

[Remi Forax]

Brian explicitly ask me to not talk about invokedynamic so i will not say that there is already an existing protocol between invokedynamic and a user defined implementation, it's the bootstrap method, 

Let's talk about the elephant in the room: macro. 
Templated Strings as currently defined is indiscernible from a hygienic String based macro system [1]. 

Using javac as an API (like jshell does), it seems trivial to come with something like EVAL."\(a) + \(b)" being able to evaluate at runtime any Java expressions. 

I'm not sure if it's a good thing or a bad thing.
