I must have gremlins today.  I'm breaking all kinds of programs.

At first, copying and pasting this code gave me a syntax error.  
Changing the above to:

        words[pos]<<number[pos,1]
        if !positions.include?([pos+1,false])

Seemed to fix that issue.

Then when I would try:

$ echo '873.7829' | ruby wordizer.rb -d /usr/share/dict/words

The above chunk of code would issue an "Illegal Seek" error.  
Commenting out ARGF.pos seem to get me over that hump.

However at that point, issuing the same command seems to cause an 
infinite loop.  I couldn't figure out what was going on there, so I 
gave up.

Just thought I would share, in case I uncovered anything...
