   I'd be an honored piggy.  After all, you and Andy are the ones
who convinced me to learn Ruby.  And your books have taught
me a lot about being a programmer.

   I learned about the matrix problems on a small English
corner of a Japanese Ruby site: apparently these problems
are well known in some circles.  I may even have copied my
matrix example from them verbatim...I can't recall for
sure.  Anyway, the matrix.rb problems are the most serious.
You can't correctly calculate the determinant of a matrix with
integer entries, even though it is a well-defined integer
result.  matrix.rb is downright broken without mathn.
