I give examples of expressivity in my comment above. The multiple dispatch is completely ubiquitous in Julia, being the default. This allows for the definition of flexible and extensible interfaces similar to Haskell's typeclasses. Macros are used to make things like PyCall or generate fast and flexible CUDA code. This is not easily possible in Python, especially not with high performance.
