Reading a variable line by line with while loop

This method has gotchas though, and I try to avoid it.  The pipe
causes the while to execute in a sub shell and so any variable changes
you make inside the loop will be lost when you get out of the loop.
For this reason I often actually create a file and do the redirect as
per the original post

e.g.

while stuff
do
done < file
