For example, breaking this code into smaller functions could make it
transparent that 'token' is only used in 'ast1', 'title' is only used in
'headers1' and that the 'mv' that is the argument to 'write_period' is only
used in the Nothing branch of the massive case statement.

It seems there are a number of straightforward ways to make this code much
clearer that do not require non-recursive let.
