    Ok, see, here's the thing.  I look at the Ruby code and can kind of follow
it.  I look at the Python code and can kind of follow it.  but in neither case
have I, in glancing here and there today, been able to decipher exactly what
is going on.  Care to show the 5 line long form to see if I get that?  No
explination, just curious to see if I can get it reading real code instead of
hacked up line noise.
