+.SH NAME
+autodie::Scope::GuardStack \-  Hook stack for managing scopes via %^H
+.SH SYNOPSIS
+.IX Header "SYNOPSIS"
+.Vb 3
+\&    use autodie::Scope::GuardStack;
+\&    my $stack = autodie::Scope::GuardStack\->new
+\&    $^H{\*(Aqmy\-key\*(Aq} = $stack;
+\&
+\&    $stack\->push_hook(sub {});
+.Ve
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+This class is a stack of hooks to be called in the right order as
+scopes go away.  The stack is only useful when inserted into \f(CW\*(C`%^H\*(C'\fR
+and will pop hooks as their "scope" is popped.  This is useful for
+uninstalling or reinstalling subs in a namespace as a pragma goes
+out of scope.
+.PP
+Due to how \f(CW\*(C`%^H\*(C'\fR works, this class is only useful during the
+compilation phase of a perl module and relies on the internals of how
+perl handles references in \f(CW\*(C`%^H\*(C'\fR.  This module is not a part of
+autodie's public API.

+.IX Subsection "Methods"

+.IX Subsection "new"
+.PP
+.Vb 1
+\&  my $stack = autodie::Scope::GuardStack\->new;
+.Ve
+.PP
+Creates a new \f(CW\*(C`autodie::Scope::GuardStack\*(C'\fR.  The stack is initially
+empty and must be inserted into \f(CW\*(C`%^H\*(C'\fR by the creator.

+.PP
+.Vb 1
+\&  $stack\->push_hook(sub {});
+.Ve
+.PP
+Add a sub to the stack.  The sub will be called once the current
+compile-time "scope" is left.  Multiple hooks can be added per scope
