this last point is misleading enough to be basically false. python has a library to do multiple dispatch, but the hard parts of multiple dispatch isn't the feature, it's making it fast enough to be usable. the python library only works at run time, which means ever function call using it will take at least a few microseconds. this is ok for niche use cases, but it's 1000x too slow for general use. the reason multiple dispatch in Julia is actually powerful is that the compiler can resolve almost all of the dispatches at compile time, so you don't have to pay for them at runtime.
