the real world of Haskell books (Re: [Haskell-cafe] Online Real World Haskell, problem with Sqlite3 chapters)

Now that is "real world" - problems even before release!-)

Seriously, though, what is the RWH authors' plan for tackling
the eternal frustration of Haskell book authors, a moving target?

There used to be a time when one could guess the poster's
Haskell book from their question topics:

    - 'HGL' doesn't work: Hudak's book
    - 'fromInt' issues: Thompson's book

The problem arises because the books survive far longer than
the version of the code base they refer to. The only way to reduce 
this friction has been to avoid fast-changing details, eg, focussing 
on programming, problem solving, reasoning (Hutton, Thompson,
Bird), and even that isn't safe ('n+k', 'fromInt',..). Neither is 
keeping a separate library - 'SOEGraphics' has been revived 
several times, on different GUI/graphic libs, even different Haskell
implementations, but has always fallen prey to bitrot again.

I've only scanned RWH briefly, but it seems to be on the other
end of the spectrum, focussing precisely on the details of stuff
that is likely to evolve much faster than the book. Is the plan to
keep someone employed over the years to keep the online
version updated?
