hello, thanks for your replies. i browsed thrugh the discussion on the libraries list, but it mainly seems to discuss if one should use bits or bytes in the binary representation. not that this is not important (my personal preference is to be fast rather then small, within reason), but i wa

Problem with hierarchical libraries in Hugs compared to ghc/nhc98

2003-03-07 Thread Olaf Chitil
When trying to make our Haskell tracer Hat work with Hugs (November 2002) I noticed that * Hugs' implementation of hierarchical libraries differs from those of ghc and nhc98, and * Hugs' implementation choice makes it more restrictive than ghc/nhc98 A simple example: There is module B in file

Pertinent to this thread (though perhaps overkill) is the work of Flajolet et al on (fast) random generation of combinatorial structures for any structure given as a context-free grammar, including Permutation. In particular see http://citeseer.nj.nec.com/flajolet93calculus.html http://citeseer.nj
