The valid_array gem provides to create an Array that enforces certian properties. Each element added to the array is passed to a validator function written by you. This function can raise errors, drop items or change them. vaild_array also provides compatibility with the typed-array gem. There is both 'valid_array/typed_array' which imports to `ValidArray::TypedArray` and a fully compatible 'valid-array' which passes 'valid-array's own test suite.

All methods that alter the contents of an array that implements this Gem are first checked to ensure that the added items are of the types allowed. All methods behave exactly as their Array counterparts, including additional forms, block processing, etc.
