Can I work on this issue?

[SophieTech88]

I noticed that the file expressions/Literal.java includes the comment: @deprecated This interface will be removed. Additionally, there’s a folder expressions/literals/ containing two files: Literal.java and Literals.java.

For the Python client, which of these files should I implement? Should I focus on the new implementation in expressions/literals/, or is there a need to maintain compatibility with the deprecated interface?

Another question: under the expressions folder, there are several subfolders like distributions, sorts, transforms, and literals, as well as files such as Expression.java, FunctionExpression.java, Literal.java, NamedReference.java, and UnparsedExpression.java.

Could you confirm if all of these need to be converted into Python client interfaces, or are there specific ones I should focus on?
