All() on Hash should have option to return tuples of the relative key and value rather than just the values.

[StuartFarmer]

Either have all spit out the keys on default, or have a method to allow it. Right now, it just spits out the values which is alright, but hard to do anything useful such as filtering, updating over specific sets based on retrieval, etc.

Expected behavior:

balances = Hash()
balances['stu'] = 100
balances['raghu'] = 100
balances['tejas'] = 100

for k, v in balances.all():
    if k == 'tejas':
        balances[k] = 1_000_000
