source code available for Purely Functional Data Structures

[Chris Okasaki]

After many requests, I've placed the source code for my book Purely
Functional Data Structures on-line.
See
    http://www.cs.columbia.edu/~cdo/pfds-sml.tar.gz
or
    http://www.cs.columbia.edu/~cdo/pfds-haskell.tar.gz

Enjoy,
Chris
