No, "?ProductLog" certainly does NOT answer my question! It tells what ProductLog DOES, not how that function is actually computed in Mathematica, i.e., what it IS in that sense! Does Mathematica have some InterpolatingFunction form stored for ProductLog? Does it calculate values of it on the fly by using an NDSolve (on the differential equation that the documentation about the function mentions)? Something else? What?
