Repeat syntax addition

[Mike Bonner]

Yeah, kinda makes sense that it would work that way. Grab the data from the
container once, do magic things behind the scenes to get it ready to go,
then loop through the lines.  I guess it could work either way though,
where it uses byte offsets to get the next chunk, which would have made the
function method really suck for large data sets.

Now I'm curious.. what exactly does repeat for each do?  Split on cr, sort
the keys and increment each loop to pop out the right line from the array?
Store all the data in a temp variable and read each line (item, char) by
start/end position?
