haskell-src-exts-util

A small suite of helper functions for working with haskell-src-exts:

• Free variables
• Bound variables
• Minimal (approximate) rebracketing of AST values such that prettyprint roundtrips.

This package extracts some the HSE functions in HLint and generalizes them. The original code was authored over the years by Neil Mitchell and the rest of HLint contributors.
