There was a posting about this some time back:

http://www.erlang.org/ml-archive/erlang-questions/200010/msg00112.html

As I understand it the problem with what you suggest (which is the same for
vectors) is that the current garbage collector relies on the unidirectional
nature of erlang and doesn't have any way to go back and deal with
destrctively updated stuff. Or something like that.

There was some stuff about this in the thread:
