ouch, this is not as clear as my solution. see mike, most of the times
i don't have a simple list to display, i have a list with a text an 
hyperlink and a datetime object to format for each item or a table row 
to populate... that's why i prefer to directly loop over the sequence 
and do whaterver is more appropriate for the context.

these pretty great and general-purpose enough to copy/paste
on my projects ^__^

thanks a million.
