You're welcome.  I thought it would be an interesting experiment.

Yes and no.  There is not longer an immediate conflict when a problem 
uses the traditional Matrix class.  But if a problem author would want 
to use both the new parser and the old matrix class in the same 
problem, then loading "Parser.pl" would cause a conflict.  But the 
conflict is only with the subroutine called "Matrix()" not with the 
classes themselves.  In that case, you could call Matrix->new() to get 
the matrix rather than "new Matrix()".  So it is not such a serious 
problem as it might have seemed at first.
