What other factors do you see contributing to that in Python?  (I've 
learned Python, but once I learned about Julia, never looked back at it).
Are there any other impediments in Python to being able to write large 
scale reliable systems (which is precisely what my colleagues and I are 
trying to do), that are currently in Julia?

However this will be very difficult to convince enough of the core

That would be fine - I don't know enough about Julia 
meta-programming  (that's next on my list of things I need to grok) to even 
know if it could be done as a macro.

I just repeated it (from: 
https://groups.google.com/d/msg/julia-users/sk8Gxq7ws3w/mvQbIb-FjRkJ), and 
if so, by the same token, people should stop using the "consenting adults" 
metaphor, which is *precisely* what leads to the "private parts" metaphor. 
 Note: https://groups.google.com/d/msg/julia-dev/Rj1xkrZkgcw/VE0K8Ji83QcJ, 
this has been around in Julia for years.
In order for the "consenting adults" metaphor to work, you have to have the 
means of *denying* consent, if you so wish.
