Is your feature request related to a problem? Please describe.
Many features are of map value that have features that have non-string keys like timestamps or uuids. Think about map of purchases by transaction_id.
Describe the solution you'd like
I would like a new type that is a map with non-string, scalar key types.
Describe alternatives you've considered
We can convert non-string keys to strings but then there is no way to convert them back.
