Hmmmm...if you add a new method,

for ch in string.as_sequence():
	muck w/ the character ch

You'd solve this.

But you won't manage to convince me that you haven't used things like

string[3:5]+string[6:] to get all the characters that...

The real problem (as I see it, from my very strange POV) is that Python
uses strings for two distinct uses:

1 -- Symbols
2 -- Arrays of characters

"Symbols" are ``run-time representation of identifiers''. For example,
getattr's "prototype" "should be"

getattr(object, symbol, object=None)

While re's search method should be


Of course, there are symbol->string and string->symbol functions, just as
there are list->tuple and tuple->list functions. 

BTW, this would also solve problems if you want to go case-insensitive in
Py3K: == is case-sensitive on strings, but case-insensitive on symbols.
