Attention - Some Facts About DSLs

A DSL is not a general-purpose programming language.

A DSL...

• must be defined like any formal language
• requires translation to a target system
• may not be as powerful as the target system's native language
• is not necessarily based on a natural language
• needs at least a vestige of knowledge about programming (except in trivial cases)
• may even require the skills of a good programmer
• an implementation causes additional development effort

A DSL is neither a silver bullet nor a free lunch.
