in reply to Payment changer

1 small comment i'd like to make is on the following part:
sub add { my $self = shift; my @units = @{ $self->{units} }; my %pieces = %{ $self->{bills} }; my $temp = shift;
I personally use the guideline that it's best to clean out @_ and assign all the values that i need before doing anything else. 9 out of 10 times this is completely unnecessary, but consistently doing it does prevent me from leaving things in @_ only to have them changed later, yielding unpredictable results. so my advice would be to start off with my ($self, $temp) = @_; and then to proceed with the remainder of the sub.

[stevieb]: perldigious: video near our hq in Montreal. Here in Calgary, it's -28c... we've only got 3" of snow so far, but there are several feet in the mountains already
[perldigious]: Snowshoeing time stevieb? I need to buy a pair so I can walk my German Shepherd properly through the country.
[stevieb]: yeah, I snowshoe a fair amount in the mountains. I also use spikes similar to these very often as well
[perldigious]: Discipulus: alternate link
[stevieb]: LOL you can easily replace "Helsinki" with "Alberta"
[perldigious]: I used to live at the top of a very steep hill stevieb, I can relate to the video. Literally used to have to build up momentum and try to force my vehicle to make it up the hill to park in my driveway properly... didn't always make it.
