In this session we identify and discuss some recurring problems and challenges in textual DSL design:

• What problems do we have to solve if we want to create a language library to enable reuse and mix-in existing languages?
• How does linking work and how can we establish crosslinks between different languages?
• What about static analysis, how is that described best and does mix-in of languages allow for reuse of existing compiler checks?
• What are the advantages and disadvantages of interpreters as opposed to compilers?
• How can we reuse existing generators or interpreters based on mixed-in languages?

During the session we'll try to find answers to these questions and show how existing frameworks help solve these problems by providing appropriate abstractions and tooling support.
