VERSION

version 0.21

SYNOPSIS

on_scope_end { ... };

DESCRIPTION

This module allows you to execute code when perl finished compiling the surrounding scope.

FUNCTIONS

on_scope_end

on_scope_end { ... };

on_scope_end $code;

Registers $code to be executed after the surrounding scope has been compiled.

This is exported by default. See Sub::Exporter on how to customize it.

PURE-PERL MODE CAVEAT

While Variable::Magic has access to some very dark sorcery to make it possible to throw an exception from within a callback, the pure-perl implementation does not have access to these hacks. Therefore, what would have been a compile-time exception is instead converted to a warning, and your execution will continue as if the exception never happened.

To explicitly request an XS (or PP) implementation one has two choices. Either to import from the desired implementation explicitly:

use B::Hooks::EndOfScope::XS
  or
use B::Hooks::EndOfScope::PP

or by setting $ENV{B_HOOKS_ENDOFSCOPE_IMPLEMENTATION} to either XS or PP.
