This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

A Sieve is a data type with properties analogous to a physical Sieve and it is useful for building up lists of data wherein a specific constraint must be met that cannot be achieved using normal type semantics. A Sieve encapsulates a list that can only hold a certain type, specified by a identity function and is preferable to creating or building up lists by using conditional blocks or by the progressive use of filter. This is especially advantageous if a list is to be passed around and used as an accumulator. In such a configuration, the original declaring type is passed around with the Sieve so that it can be used transparently in subsequent areas of the program.
