<i18n dev> RFR: JDK-8285932 Implementation of JEP 430 String Templates (Preview) [v57]

[Jim Laskey]

> Enhance the Java programming language with string templates, which are similar to string literals but contain embedded expressions. A string template is interpreted at run time by replacing each expression with the result of evaluating that expression, possibly after further validation and transformation. This is a [preview language feature and API](http://openjdk.java.net/jeps/12).
