So, this has probably been asked before, but out of curiosity, given:

	 instance IsList Text where
		type Item Text = Char
		fromList = Text.pack
		toList   = Text.unpack

What is the relationship to OverloadedStrings?  Since "blah" is sugar for 
['b','l','a','h'], could OverloadedLists also work for string literals 
/ string patterns?
