Lisp's Influence on Ruby

- Ruby was designed starting from a simple Lisp, with features like macros and s-expressions removed, and object-oriented elements added.
- Influential Lisp-derived features in Ruby include method names ending in '?' for predicates, closures and blocks as first-class functions, and symbols for fast comparison and reflection.
- Ruby's collection methods like map, select, and reduce are direct descendants of Lisp's functional programming constructs, enabling expressive, chainable operations.
- Lazy enumerators in Ruby, inspired by Lisp's lazy evaluation, allow efficient handling of large or infinite collections by computing elements on demand.
- Ruby supports duck typing and expression-oriented design, where every statement returns a value, emphasizing behavior over identity and composability.
- Metaprogramming in Ruby, through features like define_method and class_eval, reflects Lisp's 'code as data' philosophy, enabling dynamic code generation and DSLs.
- Ruby blends functional and object-oriented paradigms, allowing developers to choose abstractions based on the problem, similar to how Lisp integrates both approaches.
