libtie-hash-indexed-perl - 0.08+ds1-1+b2 main

This module implements an ordered hash, meaning that it associates keys
with values like a Perl hash, but keeps the keys in a consistent order.
.
Tie::Hash::Indexed is intentionally very similar to other ordered hash
modules, most prominently Hash::Ordered. However, Tie::Hash::Indexed is
written completely in XS and is, often significantly, faster than other
modules. For a lot of operations, it's more than twice as fast as
Hash::Ordered, especially when using the object-oriented interface instead of
the tied interface. Other modules, for example Tie::IxHash, are even slower.
.
The object-oriented interface of Tie::Hash::Indexed is almost identical to
that of Hash::Ordered, so in most cases you should be able to easily replace
one with the other.
