Your taxonomy has little to nothing to do with real life usage.
You got to be able to demonstrate that there is anything you can do more elegantly in Python than in Julia. I can scarecely think of anything.
Yes, real implementation inheritance is sometimes nice. Yet for the most part I find Julia to be a better Python than Python.
Throwing Julia in the same bucket as C++ and Fortran makes absolutely no sense. It makes me wonder if you have even tried the language.
I will claim that Julia is a better language at automation than Python. Shell integration is much better in Julia. It integrates with C/C++ better than Python. It integrates with Fortran, R and Python as well.
The COM example I cannot say I grasp. What unique feature does Python have that Julia doesn't which makes a COM bridge possible?
There are lots of things Python will be better at than Julia today simply due to libraries. However I cannot think of anything that is related to the language as such.
Library advantages Python has over Julia will slowly errode over time. Julia package development moves fast.
