Rascal is a programming languages geared towards language processing:

• the backbone is procedural/functional programming with immutable data
• abstract and concrete grammars define parsers and hierarchical data-types
• relations and relational calculus provide database/logic query functionality

Here we briefly introduce the most relevant skills by example:

• Source Comments
• Static Typing
• Datatypes
• Immutable Values
• Enumerating
• Comprehensions
• Pattern Matching
• Control Structures
• Case Distinction
• Visiting
• Functions
• Syntax Definition And Parsing
• Rewriting
• IDEConstruction
• Code Models
• Equation Solving

The reference manual spells out all syntax and semantics organized per language feature.
