Hi,
I have a product feed with a number of properties (size, shape, colour, etc.). Each property has values (size has S,M,L etc., shape has circle, square etc., colour has red,white, blue, etc.) I.e., both the properties and values are variable.

Based on these I want to create all possible combinations, for example "Blue circle size S","Blue square size S" etc, but I don't know how to do it. For now I'm storing in an HoA:
my %Properties;
...

# Outer loop, per $property_id
# Inner loop, per value of property:

push @{ $Properties->{$property_id} }, 
{
   'Value' => $value,
   'Price' => $price,                    
};

Ideally, I want to loop the Properties-hash and create the combinations from that. I know how to do it in a static fashion (Defining a number of arrays and looping them), but how to do it dynamically?
