DESCRIPTION
This module provides package-related utilities. You should check
Package::Stash first, then here.
FUNCTIONS
package_exists
Usage:
package_exists($name) => bool
Return true if package "exists". By "exists", it means that the package
has been defined by "package" statement or some entries have been
created in the symbol table (e.g. "$Foo::var = 1;" will make the "Foo"
package "exist").
This function can be used e.g. for checking before aliasing one package
to another. Or to casually check whether a module has been loaded.
list_subpackages($name[, $recursive]) => @res
List subpackages, e.g.:
(
"Foo::Bar::Baz",
"Foo::Bar::Qux",
...
)
If $recursive is true, will also list subpackages of subpackages, and so
on.
