Perhaps this would be a good moment to advertise the revised version of

	Tackling the Tackling the Awkward Squad:
	monadic input/output, concurrency, exceptions, 
	and foreign-language calls in Haskell

	http://research.microsoft.com/~simonpj/#marktoberdorf

(Concerning the thread I'm responding to, it gives an introduction 
to monadic input/output.)

I've revised and extended this tutorial quite a bit since I announced it
last year,
with a lot of help from people on the Haskell mailing list: thank you!
Further suggestions are most welcome.

	Abstract

	Functional programming may be beautiful, but to write real
	applications we must grapple with awkward real-world issues:
	input/output, robustness, concurrency, and interfacing to programs
	written in other languages. 

	These lecture notes give an overview of the techniques that have
been
	developed by the Haskell community to address these problems.  I
	introduce various proposed extensions to Haskell along the way, and
I
	offer an operational semantics that explains what these extensions
	mean.
