## What it is
goderive is a Go code generator that derives mundane functions (like Equal, Compare, DeepCopy, Sort, Hash) from their parameter types. It parses unimplemented functions with a 'derive' prefix and generates their implementations into a derived.gen.go file.

## Use cases
- generate equality functions for Go structs
- auto-generate deep copy functions in Go
- derive sort and hash functions from types
- avoid manually maintaining boilerplate Go functions
- generate set operations like union and intersect for Go types
- derive memoization and function composition helpers

## When to choose
- you write Go and want type-derived boilerplate functions generated automatically
- you prefer generated code over reflection for performance
- you want a Haskell-style deriving workflow in Go

## When to avoid
- you prefer runtime reflection or generics-only solutions without code generation
- your project disallows generated code files
- you need dynamic behavior that cannot be derived at build time
