However, it would be difficult to do that without changing
all C code that deals with strings, including that in extension
That's because the existing string type stores the characters
in the string object itself. A mutable variant would have to
contain a pointer to a resizable memory block, and therefore
couldn't be used as a drop-in replacement by existing C
code that expects a string.
