coming from C I'm confused about this behavior in assignment:
Since you know C, it may make sense to think of lists as being

that makes sense - I guess I was expecting lists to behave like list
*classes* which have an overloaded assignment operator.
Turning this around: is there a 'list-like' data type in sage which
has 'true' assignment, i.e. copying all its content ?
Python inherits a lot from C. It is practically nothing like C++
(despite both being object oriented). There's no such thing as
assignment overloading--everything is heap allocated and you're just
passing around references under the hood.
Try doing
sage: import copy
sage: copy.<tab>
to if some of the functions there work for you.
