Thank you. I'll have a read of those. I didn't mean to suggest you
should have given all the details, just that haskell.org confused
me by saying mdo didn't exist.

I've just tried some other words from that page in the Search box and
couldn't see any pattern to whether the page appears in the search
results. Very strange. Maybe a message along the lines of "We are
hoping some generous person will improve this search feature at some
point. The source code is here ... The search currently produces
incomplete results. Please try Google if you do not find an answer."
would be useful?
