deBruijn sequences

[Wayne Young]

Was wondering if there was a simple Haskell function/library for producing
"simple" base-2 deBruijn sequences.  I have a clean seven line function in
NESL, but have no chance in Hades of being able to compile/use NESL with my
resources.  Haskell-wise, I'm using Hugs98.


Thanks,
    Wayne
