Creating and using domain-specific language features

The value that domain-specific languages provide to their users is the domain-specific language features they contain. These features provide notations from the domain of interest, as well as domain-specific analysis and optimizations. But domain-specific languages are sometimes a poor means of delivering these valuable features to their users. A challenge arises when a problem crosses multiple domains and whose programming or modeling solution could benefit from language features from all domains of interest. Using multiple domain-specific languages can become cumbersome, perhaps outweighing their benefits in the first place.
