AST tree line numbers

AST tree line numbers

Hi, 

I'm using pandoc to parse Markdown input to AST, make some actions based on 
Markdown input's contents and then make some tiny alteration to the input 
files.
The issue is: this flow doesn't work for me:

AST -> my filter -> AST -> output.md


because Pandoc generates Markdown that differs in style from my original 
.md files
So the question is: will Pandoc ever include line numbers in it's AST trees 
for more convenient changing of files? 

This node.js library does that: https://astexplorer.net/ (I'm not using it 
because it does not recognize LaTeX formulas properly)

Are there any workarounds apart from counting characters in the AST nodes?

The Haskell commonmark library I'm working on does track
source positions, so once this is integrated into pandoc
we should be able to do this.  It may take a while though.
