# The pqueue-mtl package

Deprecated in favor of queuelike

Contains several implementations of data structures implementing a *single-in, single-out* paradigm,
and implements monad transformers for their safe use. The monad transformer part of the library
includes tools to fully encapsulate single-threaded use of a priority queue in a monad, including an
array-based heap implementation.
In general, the purely functional queue types can be ordered in increasing order of speed on generic insertion/deletion operations
as follows: `Stack`, `Queue`, `PQueue`, `IntQueue`, `SkewQueue`, `FQueue`, `Heap`.
(`PQueue`, `IntQueue`, and `SkewQueue` are all very nearly the same speed.)
Work is in progress on a van Emde Boas
or y-fast priority queue implementation, which provides sublogarithmic functionality for all operations.
