How do I use the Tango LineIterator.scan()?

Quite so, Alexander, and that's what I switched to in my code.  I 
refactored what I had and switched to commas, just in case someone uses 
whitespace to pad things. ;-)

And if you know what exercise 9 is on the site, you have variable input. 
  Which does make it a fun experience.  My constructor just takes the 
line and parses it, so it's quite convenient.

I wound up with:

And I use the LineInput object in the parent class to read and iterate 
through the lines.

I must say that I like D and the Tango library. =)
