NAME
Symbol::Util - Additional utils for Perl symbols manipulation
SYNOPSIS
use Symbol::Util ':all';
my $caller = caller;
*{ fetch_glob("${caller}::foo") } = sub { "this is foo" };
my $coderef = fetch_glob("${caller}::bar", "CODE");
sub baz { 42; }
export_glob($caller, "baz");
print join "\n", keys %{ stash("main") };
delete_glob("${caller}::foo", "CODE");
use constant PI => 3.14159265;
delete_sub "PI"; # remove constant from public API
require YAML;
export_package(__PACKAGE__, "YAML", "Dump"); # import YAML::Dump
unexport_package(__PACKAGE, "YAML"); # remove imported symbols
no Symbol::Util; # clean all symbols imported from Symbol::Util
DESCRIPTION
This module provides a set of additional functions useful for Perl symbols manipulation.
`stash' and `fetch_glob' functions gets stash or glob without need to use `no strict 'refs''.
`delete_glob' function allows to delete specific slot of symbol name without deleting others.
`delete_sub' removes the symbol from class API. This symbol won't be available as an object method.
`export_package' works like Exporter module and allows to export symbols from one package to other.
`unexport_package' allows to delete previously exported symbols.
