As Thomas Hartman noted in a recent cafe thread , haskell 1.3
included the functions 'subsequences' and 'permutations'. I think these
functions are quite useful, and I don't know why they were ever removed.
This is a proposal to add these two functions to Data.List. The
implementation is taken directly from the Haskell 1.3 report .
Trac ticket: #1990
Discussion period ends: January 7th (since there is a holiday comming up)
