sure. but why do we need text processing in scripting? because the usual OS shells have `string' as their only data type. we better change that :-) anyone for a fully typed Haskell shell?
I am sorry, but I couldn't resist answering your question: have a look at Arjen van Weelden's Famke system [1,2], who has done exactly that (in Clean):
