úÎ'C$±'      !"#$%&'()'()'()() Like MonadIO, but for *. This allows JSON parsing 9 operations to be lifted into our various view monads. IAttempts to parse a JSON value into a given type. This is typically used N with a type annotation to indicate the target type. If the value can not A be parsed into that type, the entire computation will fail. Applies  5 to a list of values. This is commonly used with the  reduce function arguments. JParses a required field of an object. If the field is not present, or the N value can not be parsed into the target type, the computation will fail. JParses an optional field of an object. This will not halt the computation  on failure.     +,MThe type of your reduce functions as they are stored in CouchDB. The trivial  example: & \keys values rereduce -> return Null CThe monad within which a reduce computation takes place. This is a  transformation of the * monad, which is accessible  through the   typeclass. -.JSend a log message to the CouchDB server. Note that log messages are only Q sent if the computation succeeds. If you want to log a message in the event  of a failure, look at /.   JThe type of your map functions as they are stored in CouchDB. The trivial  example:  \doc -> return () @The monad within which a map computation takes place. This is a  transformation of the * monad, which is accessible  through the   typeclass. 01 !"#$ Emit a key/?value pair for the current document.
