Description:
like ref() but useful
Scalar::Does provides a "does()" built-in. . A check that "ref($thing) eq 'ARRAY'" doesn't allow you to accept an object that uses overloading to provide an array-like interface. . This package also includes IO::Detect, for detecting if a scalar is a filehandle (or something filehandle-like).
