## What it is
Skip is a statically typed, ahead-of-time compiled general-purpose programming language that tracks side effects to enable safe memoization with reactive cache invalidation, safe parallelism, and predictable garbage collection. It compiles via LLVM and ships as a toolchain (compiler, runtime, and bundler) usable directly or through a Docker-based development environment.

## Use cases
- build a programming language with automatic caching of pure computations
- write parallel code without thread-safety bugs
- learn a hybrid functional/OO statically typed language
- experiment with reactive invalidation of cached data
- compile a language to optimized native executables with LLVM
- try a language with predictable garbage collection

## When to choose
- you want safe memoization driven by type-system proofs of purity
- you need ergonomic async and parallel computation without shared mutable state
- you want predictable, low-overhead GC behavior
- you are exploring novel language design around side-effect tracking

## When to avoid
- you need a production-ready language with a large ecosystem and libraries
- you want quick drop-in tooling for an existing codebase
- you require long-term support or frequent updates
- you are not prepared to use Docker or build the toolchain yourself
