ghc-dup

Explicitly prevent sharing.

This package provides two new operations, GHC.Dup.dup and GHC.Dup.deepDup, that allow the programmer to prevent the result of two evaluations of the same expression to be shared.

See http://arxiv.org/abs/1207.2017 for more background.

This is still experimental software and can likely cause your program to crash.

The work on this package has been supported by the Deutsche Telekom Stiftung (http://telekom-stiftung.de).
