- B
The result type of your secondary ValueMapper.
- fa
A secondary ValueMapper to try if the first one fails.
- returns
A ValueMapper that, if sucessful, will return a value of either the original or secondary type.

- B
The result type of your new ValueMapper from your function.
- f
A function that returns a new ValueMapper.

- AA
A type that is possibly a supertype of your original ValueMapper type.
- mapper
A ValueMapper to use if the current one fails.
- returns
A new ValueMapper that returns the type of the supplied secondary mapper.
