[Haskell-cafe] Functional references

[Tim Newsham]

I'm playing with functional references and looking for some feedback on a 
small FRec library I put together:

   http://www.thenewsh.com/~newsham/FRef.hs

Novel (I think) is that the library is applied to some data accesses that 
are not normally covered by functional references -- ie. extracting words 
or replacing words in a string or values in an association list.  I'm 
hoping it will provides a useful framework for editing complex values such 
as data embedded in Base64 cookies in an HTTP header.
