Hello fellow Monks,

I am getting the error ...

Operation `bool': no method found, argument in overloaded package Vector2D at

... and here's the pertinent code snippets ...

package Vector2D; use strict; use Exporter; use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS); use overload "-" => \&minus, "+" => \&plus, "*" => \&mult;

... here's the snippet from the script that uses Vector2D ...

sub drawPoly { my @p = @_; #Array of Vector2Ds my $start_point = pop( @p ); while( pop( @p ) ) { $can->create( 'line', $start_point->getx(), $start_point->gety(), $_->getx(), $_->gety()); $start_point = $_; } }
The line number mentioned in the error message
coresponds to this line ...
while( pop( @p ) ) {
... Oh! Wise Monks why has this pestilence befallen me!
