(Phils machine goes --bleep--)

I *was* going to mention about <dtml-raise > but I knew Phil would be 
lurking, and he doesn't get out much! :)

To add *some* content to this mail, I *think* you can do _.xrange() 
too, so that largeish loops can also be done...checking 
source....(DT_Util.py) nope. I was wrong. No xrange, but _.range() 
has got a limit of 1000, so you won't be doing any infinite loops 
using *that* function...
