+ <p>
+ The function removes the <c><anno>Key</anno></c>, if it exists, and its associated value from
+ <c><anno>Map1</anno></c> and returns a tuple with the removed <c><anno>Value</anno></c> and
+ the new map <c><anno>Map2</anno></c> without key <c><anno>Key</anno></c>.
+ If the key does not exist <c>error</c> is returned.

+ <p>
+ The call will fail with a <c>{badmap,Map}</c> exception if <c><anno>Map1</anno></c> is not a map.

+ <code type="none">
