  4. (.:++) :: PushR n m => RangeR n (m - 1) a -> a -> RangeR n m a

    ranged-list Data.List.Range

    To push an optional element. 

    >>> :set -XDataKinds

>>> samplePushR = NilR :++ 'h' :+ 'e' :+ 'l' :+ 'l' :: RangeR 3 7 Char

>>> samplePushR .:++ 'o'
((((NilR :++ 'h') :++ 'e') :+ 'l') :+ 'l') :+ 'o'

>>> :type samplePushR .:++ 'o'
samplePushR .:++ 'o' :: RangeR 3 8 Char

  5. (.:..) :: PushL n m => a -> RangeL n (m - 1) a -> RangeL n m a

    ranged-list Data.List.Range

    To push an optional element. 

    >>> :set -XDataKinds

>>> samplePushL = 'e' :. 'l' :. 'l' :. 'o' :.. NilL :: RangeL 3 7 Char

>>> 'h' .:.. samplePushL
'h' :. ('e' :. ('l' :. ('l' :.. ('o' :.. NilL))))

>>> :type 'h' .:.. samplePushL
'h' .:.. samplePushL :: RangeL 3 8 Char

  7. (.!=) :: Parser (Maybe a) -> a -> Parser a

    safe-json Data.Aeson.Safe

    Helper for use in combination with .:? to provide default values for optional JSON object fields. This combinator is most useful if the key and value can be absent from an object without affecting its validity and we know a default value to assign in that case. If the key and value are mandatory, use .: instead. Example usage: 

    v1 <- o .:? "opt_field_with_dfl" .!= "default_val"
v2 <- o .:  "mandatory_field"
v3 <- o .:? "opt_field2"

  8. (.:) :: FromJSON a => Object -> Key -> Parser a

    safe-json Data.Aeson.Safe

    Retrieve the value associated with the given key of an Object. The result is empty if the key is not present or the value cannot be converted to the desired type. This accessor is appropriate if the key and value must be present in an object for it to be valid. If the key and value are optional, use .:? instead.

  9. (.:!) :: FromJSON a => Object -> Key -> Parser (Maybe a)

    safe-json Data.Aeson.Safe

    Retrieve the value associated with the given key of an Object. The result is Nothing if the key is not present or empty if the value cannot be converted to the desired type. This differs from .:? by attempting to parse Null the same as any other JSON value, instead of interpreting it as Nothing.

  10. (.:!=) :: FromJSON a => Object -> Key -> Parser a

    safe-json Data.Aeson.Safe

    Retrieve the value associated with the given key of an Object. If the key is not present and the omittedField is Just x for some x, the result will be that x. This differs from .:?= by attempting to parse Null the same as any other JSON value, instead of using omittedField when it's Just.
