How do I handle variable number of lists? I need to accept a variable number of lists and then step through all the lists at the same time. Simple example: User creates a file with: 
fruit:apple
fruit:orange
fruit:banana
veg:celery
veg:cucumber
veg:been

[download]
So I read this file into a hash of arrays but how do I go through the lists to get: 
Day 1: apple celery
Day 2: orange cucumber
Day 3: banana been

[download]
The next time this is run there could be 3 things: fruit, veg, meat...
