I have a hash in which each mapping references an array. Anyone know how I could sort the hash based on the size of the referenced arrays?

Thus:
key0 -> (f, a)
key1 -> (a, b, c, d, e)
key2 -> (g)
key3 -> (h, i, j)

From this example I want to generate the output 

key2 -> 1
key0 -> 2
key3 -> 3
key1 -> 5

I.e. The keys are sorted in ascending order based on the size of their referenced arrays (and I want to print the above keys/sizes to a text file).

Best wishes, Arun
