Smalltalk also has similar interactive development styles. One can build the application incrementally piece-by-piece. It has a residual graphical integrated development environment -> the development environment is a part of the program. It uses late-binding via message-passing. It starts and saves images (-> dumps of the heap contents, data and code). It is introspective & reflective (one can find out about the running program and can change it).
This.
Smalltalk’s metaprogramming through classes-as-objects and code-as-objects is very much comparable to Lisp’s.
Ruby is a modern example, with Pascal/Algol-like syntax with lots pf sugar. It has some very rich metaprogramming.
