Pattern matching accepted for Python

That's not exactly how C works, but I wasn't going to use C as my primary example, I was going to use Rust. You have to write "let mut" to let a variable be reassigned/mutated, and variables in Rust are almost identical to ones in Python as far as being an abstract 'namespace' binding.

Sure, I elided a bajillion details, and who knows what the CPU is doing under the hood anyway? :)

I've never used rust (yet) so I can't really comment on that.

FWIW namespaces in Python aren't abstract, they exist as dicts at runtime. You can modify the dict you get back from locals() or globals() and change your "variables" in scope:

    >>> d = locals()
    >>> d['cats'] = 'meow'
    >>> cats
    'meow'
