I will occasionally use until, but it rarely seems to be needed. I
use unless all of the time.
One reason is that you often have one variable you are testing a
while/until loop:
while ($continue) {}
until ($stop) {}
It seems natural to set the variable to true when you start and false
when you want to stop. Of course, the counter argument is that
until ($found) {}
makes more sense than
while ($notfound) {}
But I guess the habit of just adding not to the variable name is too
ingrained in me at this point.
