I'm thinking we could use these combinators:

  • indented — for things with higher indentation
  • optionalIndent — for things that are optionally indented
  • sameLevel — for things that should not be indented

Another option is to automatically insert { and } based on indentation in the tokeniser, but I'm not sure how ergonomic that would be to use.

Yet another option could be to have a more hierarchical parser, where you are explicit about parsing subtrees. Basically, each parser would take a rose-tree as input so there is no risk of confusion between indented subtrees and unindented nodes.

well, the readsheets5 branch has certainly made a lot of progress on this
