When will strings become immutable?

As it stands now we are able to go back and edit our strings, how long will this last for?

Strings are always immutable, but the variables that hold them can be re-assigned with a new value.

For examples:

s = "string"
s = "test"   # re-assignment is ok
s[2] = "x"   # but this will cause an error because the string is immutable

Not sure what you mean but as far as I know, strings are immutable unless you use concatenation, splitting etc, but you'd still need to create a new object from the original.
