I have friends who prefer (& use on the daily basis) all the technologies mentioned below - I respect all of them as not only great guys but also top-notch professionals.

REPL stands for Read Eval Print Loop & it's a common name for platform/language-specific shells that give you the ability to do live programming with line-by-line evaluation as you finish each line. In plain, soldier's words - REPL 'scriptizes' your programming language of choice to give you sort-of-debug experience without limiting you to execution of just the

What's a State pattern?
State pattern is a way to encapsulate state (& behaviour that depends upon it) within an object the state belongs to. It's a natural way to express physical reality (and its variability over time) in a conceptual
