About:
The Glasgow Haskell Compilation System (GHC) is the leading, production-ready compiler and interactive environment for the Haskell programming language. It transforms Haskell source code into optimized native executables and provides a runtime system supporting advanced language features like lazy evaluation and software transactional memory.

Key Features:

Full-featured compiler for the Haskell 2010 language standard with numerous extensions
Interactive environment (GHCi) for development, debugging, and scripting
Sophisticated optimization passes for generating high-performance native code
Comprehensive runtime system supporting concurrency, parallelism, and profiling

Use Cases:

Developing and deploying production Haskell applications and services
Academic research and teaching functional programming and language design
Building and managing Haskell libraries and packages via the Cabal or Stack ecosystems

Alternatives:

GHC (latest stable version) – This is a specific versioned formula (9.12). The latest stable GHC formula is the primary alternative for most users.
UHC (Utrecht Haskell Compiler) – An alternative Haskell compiler focused on experimentation and teaching, less feature-complete for production than GHC.
