(What am I doing trying to argue with ROK??? Am I MAD?)

1) Why is it people rant about "string handling" in Erlang?

2) Principle of least surprise:
1> [H|T] = [22,87,65,84,33].
2> H.
3> T.

3) A codec should be perfectly reversible i.e. X = encode(decode(X)). Without tagging, merely parsing out a string as a list is not perfectly reversible.

4) What is the right way to implement the function is_string(List) correctly?
