%description
'Hash::FieldHash' provides the field hash mechanism which supports the
inside-out technique.

You may know 'Hash::Util::FieldHash'. It's a very useful module, but too
complex to understand the functionality and only available in 5.10.
'H::U::F::Compat' is available for pre-5.10, but it is too slow to use.

This is a better alternative to 'H::U::F' with following features:

* Simpler interface

'Hash::FieldHash' provides a few functions: 'fieldhash()' and
'fieldhashes()'. That's enough.

* Higher performance

'Hash::FieldHash' is faster than 'Hash::Util::FieldHash', because its
internals use simpler structures.

* Relic support

Although 'Hash::FieldHash' uses a new feature introduced in Perl 5.10, _the
uvar magic for hashes_ described in Hash::Util::Fieldhash/"GUTS", it
supports Perl 5.8 using the traditional tie-hash layer.
