NAME

B::Hooks::EndOfScope - Execute code after a scope finished compilation

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

(or ) 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".
