> As Merigoux explained more fully on his blog, this project became possible because the French government open-sourced the code that they use to calculate residents’ taxes, which was written in a domain-specific language called M, but they didn’t release the compiler that would have been needed to actually run any code written in that language. MLang is a compiler for M code written by Merigoux, and it has two special features: it translates the tax calculation function to Python, and it enables formal verification of features of the tax calculation using an automatic theorem prover called Z3.
