It was fun, too. For instance, the OP's question reminded me of a little generic wrapper I wrote -- more or less for my own amusement -- during the course of this project. It outputs dots during an operation that might take a little longer to finish (a database query in my case)... just so the user doesn't get nervous ;-) And because I enjoyed it so much (and to show off) I threw in the timing measurement... [...] I think nobody in his right mind would even try to do something like that in C or Perl or whatever, at least not if it wasn't strictly a requirement and correct operation is important (the script gets executed as part of our build process and a subtle concurrency bug could lead to a wrong configuration for the target control system). In Haskell it was so easy to do that I just couldn't resist.

That's a neat idea. Just (a) because I like the idea, and (b) because I'm contrary :-) I coded up the equivalent in Python. It also looks beautifully clean: [snipped python code]

Looks good to me. I' walk back on the "or whatever" with regard to Python... ;-) Cheers Ben
