Thanks for putting this together @GuySten and sorry it has taken me a long time to look this one over. In general, I feel like the addition of the Lambert W function on the C++ side is a lot of code for something that would almost never be used. I would be comfortable adding the sampling routines on the Python side (where we already have access to lambertw from scipy) but would prefer not to include the C++ portion. If someone really needs to sample a lin-log distribution on the C++ side, I think a better option is to just linearize it first and we already have the openmc.data.grid.linearize function that can handle that.
