In the dictionary for the "repeat" control structure. ;-)

"Use the for each form if you want to perform an action on each chunk 
in a container. This form is much faster than the with countVariable 
= startValue to endValue form when looping through the chunks of a 
container."

(It doesn't go into detail about why this is so, though, and that 
would be interesting and perhaps useful information to add.) There 
also used to be some mentions of this in the cookbook, although the 
cookbook seems to have gone away.
