Technically yes, but the code would require so many changes to make
that work that I didn't think it was worth it.  I might as well call
it bills.algorithm at that point instead of std2.algorithm.
Apparently Andrei didn't like the thought of having to write the code
that way either, which is presume why he convinced Walter to
change/fix IFTI in D2.
