Is Polyglot Programming Really a Thing? (Invited Talk)

Polyglot programming is the practice of writing an application with multiple languages to capture additional functionality and efficiency not available to a single language. This happens more often than people think. Some reasons are: to support different platforms (e.g., Android, iOS), to be more efficient on some parts, to take advantage of features unique to a different ecosystem (e.g., dedicated APIs). But are we ready for polyglot programming? This talk will try to explore the open issues from the point of view of both the multiple programming language integration and from the software engineering development for polyglot programming.
