The thing that struck me about the interaction (on Python-Ideas, btw) 
was that Javascript actually is adding new language features at an 
impressive pace, and many of them seem very Pythonic.? But they 
sometimes choose different syntax.

For example, their "spread" operator is ..., where Python uses *:

 ??? new_list = [new_start, *old_list, new_end]

vs:

 ??? new_array = [new_start, ...old_array, new_end]

Making Python more like Javascript (in this case) would have required 
breaking existing Python programs. Javascript could have use * as the 
spread operator without breaking anyone. But they didn't, and I wonder 
if anyone petitioned them to keep compatibility with Python to easy the 
plight of the multi-lingual programmer.
