Thanks.  That's certainly what I intended when I added it.  I think that 
functional languages are a very interesting point on the 
power/complexity/analyseability scale, as they have all the expressive 
power of Turing completeness, but can be reasoned about in ways that are 
difficult with procedural languages.

So, I was a bit disappointed when the first response (from Harry Halpin) 
worried that the text could be taken as criticising rather than supporting 
the best aspects of functional languages.  I don't think this is worth a 
flame war, but I'll be curious to see how other readers took it.  Thanks!
