NAME
   namespace::clean::xs - Keep imports and functions out of your namespace,
   in XS

SYNOPSIS
       use namespace::clean::xs; # be lean and mean

DESCRIPTION
   This module is a much faster (~30x) alternative for namespace::clean.
   namespace::clean spends approximately 1ms per module, so it can
   significantly impact startup time for a large codebase. This module
   tries to be a drop-in replacement for it.

   See namespace::clean for a workflow description/usage examples.

COMPABILITY
   This module tries to minimize memory impact after it's usage, so it
   won't expand constant/stub functions to full globs. It also removes
   symbols without data from the package completely.

   Since version 0.27 namespace::clean allows you to clean a single package
   twice. This behaviour is not supported yet.

   While all methods from namespace::clean are implemented, individual
   functions have the following differences:

   "import"
       Will croak on unrecognized options.

   "unimport"
       Will croak on unrecognized options.

   "get_class_store"
       Structure of the returned hash is the same, but it has nothing to do
       with the internal storage. Modifications of it are in vain.

       While namespace::clean saves this info forever, this module deletes
       it after namespace cleanup is done.

   "get_functions"
       In the returned hash function stubs and constants are not expanded.
       You can't count on calling values in it as functions unless you
       access corresponding glob first (and loose any memory savings in the
       process).
