why tuple instead of list

[Skaperen]

the language i was designing before i encountered Python (i never encountered ABC) did not have distinctive types for mutable vs immutable. what it had was the ability to change any data object instance to immutable, either temporarily (can be undone) or permanently (cannot be undone). simple literals were automatically made permanently immutable. container literals were not. but you could build a mutable string or list from their creation methods. i had not done any unicode support in my language, though. if, for some reason, i were to finish it today, unicode, and many other things inspired my Python and Python3 would be added on.
