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).
