He is reinventing Chris Granger's Eve language all over again. I have seen many, many attempts at "functional-reactive programming languages with an Excel-style DB bolted on top" and not a single one has succeeded so far. The biggest reason for failure is that trying to do both tend to result in a half baked platform. The DB /spreadsheet lacks features and the programming language doesn't offer enough functionality/libraries to make apps. OP needs to make a killer application/compelling use case.
