provides a bits_is() subroutine for testing binary data
This module provides a single subroutine, bits_is(), for testing binary data. This module is quite similar to Test::BinaryData and Test::HexString in concept. The difference is that this module shows failure diagnostics in a different way, and has a slightly different calling style. Depending on the nature of the data you're working with, this module may be easier to work with.
