Dynamic key access to translations

Hi,

There are some use-cases (e.g. translations for enum types) where I need to access a dynamic key in runtime. I wonder if this can be achieved with the library without written mapping code in the client? At the moment I am using a workaround where I put the translations as map in a row, and do a runtime check and apply the items, e.g.

key: | en
enum.fruits | {"apple": "Apple", "banana": "Banana", "default": ""...}

But it is not very scalable compared to define "apple", "banana" as separate rows.
