Hi Haskellers,

I just published an article that can be interesting to lovers of functional
programming, even though it's not directly relevant to Haskell per se.

http://jkff.info/articles/ire/

It's based on Dan Piponi's blogpost "Fast incremental regular expression
matching with monoids"
http://blog.sigfpe.com/2009/01/fast-incremental-regular-expression.html but
expands Dan's ideas to include *locating* matches, matching multiple
regular expressions at once, using a more compact datastructure than
fingertrees, etc.

And - sorry - the implementation is in Java, for reasons explained in the
article :)
