in reply to Basic Objects with Overloaded Operators

This is a well written article on the wonders of overloading and OO. But I have one complaint:

unless( ref($b) =~ /\S/ ){}
Is not a good way to find out if a variable is a reference to a Complex or not. The better way is UNIVERSAL::isa(). Every OO class inherits from UNIVERSAL, and so you can always call $object->isa(), like this:
unless( $b->isa( 'Complex' ) ){}
Other then that nit-pick, this is a good tutorial.

    Thanks for the comment! I have included the isa call into
    the root node. I wasn't familiar with isa when I wrote the
    article (many moons ago).

      unless(isa( $b, 'Complex' ) ) is more proper to cover the case when $b is not an object.
