Fig is a statically-typed, expression-oriented programming language designed for clarity, safety, and modern development practices. With features inspired by Go, Rust, and JavaScript, Fig aims to provide a productive development experience while maintaining strong type safety.

Features

🚀 Core Language Features

Static typing with type inference - Strong typing with minimal annotations
Modern control flow - Full for loop support with proper scoping
First-class functions - Lambda expressions and closures
Rich data structures - Structs, lists, maps, and tuples
Memory safety - No null pointer exceptions, automatic memory management

🔧 Technical Highlights

Three-level scoping for loops - Proper variable isolation in iterations
Smart semicolon handling - Flexible statement termination with RAII guards
Comprehensive error handling - Detailed error messages with source locations
Clean C++ implementation - Modern C++23 with RAII and smart pointers

Language Philosophy

Fig is designed around several core principles:

Clarity over cleverness - Code should be readable first

Safety by default - Prevent common errors at compile time

Modern ergonomics - Developer experience matters

Gradual learning - Simple to start, powerful when needed
