Module Libsail.Chunk_astSource

Module for breaking AST into syntactic chunks and interleaving comments.

This module is part of the Sail formatting system. It takes a parsed AST (not a desugared AST, as for formatting we need to preserve as much as possible), and breaks it up into more abstract syntactic elements - 'chunks' for want of a better term.
