Strict +Control.Monad.Trans.Writer -package

module Control.Monad.Trans.Writer.Strict
transformers Control.Monad.Trans.Writer.Strict
The strict WriterT monad transformer, which adds collection of outputs (such as a count or string output) to a given monad. This version builds its output strictly; for a lazy version, see Control.Monad.Trans.Writer.Lazy, which has the same interface. This monad transformer provides only limited access to the output during the computation. For more general access, use Control.Monad.Trans.State instead.
