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.
