> I am beginning to develop a C++ API for describing analytical expressions on 
> scalars, arrays, and tables in the general style of Ibis 
> (https://docs.ibis-project.org/sql.html) which has been used to successfully 
> model SQL relational algebra as well as a broader variety of analytical 
> operations. This is a large project so I'm starting small
