I wonder how this relates to "Calc Intelligence" or "Project LAMBDA", made by Simon Peyton Jones (of Haskell fame) et al.

> By Calc Intelligence, we mean the research goal of bringing intelligence to end-user programming. The spreadsheet of the future is a trustworthy collaborator and teacher.

> In December 2020, we announced LAMBDA, which allows users to define new functions written in Excel’s own formula language, directly addressing our second challenge. These newly defined functions can call other LAMBDA-defined functions, to arbitrary depth, even recursively. With LAMBDA, Excel has become Turing-complete. You can now, in principle, write any computation in the Excel formula language.
