> surprising for me:

Surprise is subjective, it's based on personal experience. Very few
languages allow arbitrary complex expressions in the same place they
allow variable introduction. The fact that "i" is not defined is
irrelevant to this example.  Most programmers who haven't memorized
Python grammar by heart, but expect the language to behave similar to
the languages in the same category would be surprised this code is
valid (i.e. can be parsed), whether it results in error or not is of
no consequence.

I use the term "destructuring" in the same way Hyperspec uses it.
It's not a Python term.  I don't know what you call the same thing in
Python.  I'm not sure what you understand from it.
