I want to generate something like an if-elseif-else construct or switch-case programmatically.
The use I have in mind is to write an expression for taking a step in a random walk in n dimensions, so I need 2*n branches. The solution I found is not very readable. I wonder if there is an easier way to do it. The function to generate the code is here https://gist.github.com/jlapeyre/66c7714f22c66123add5db0accf1f01d The application to a random walk step is here https://gist.github.com/jlapeyre/b93bead293f903b6afb1cc5d4bd14d13
