     Functional Lexing and Parsing</p></short>

+	This talk will describe a non-traditional functional approach
+	to the classical problems of lexing (breaking a stream of
+	characters into "words" or tokens) and parsing (identifying
+	tree structure in a stream of tokens based on a grammar,
+	e.g. for a programming language that needs to be compiled or
+	interpreted). The functional approach can clarify and organize
+	a number of algorithms that tend to be opaque in their
+	conventional imperative presentation. No prior background in
+	functional programming, lexing, or parsing is assumed.
