Registers \f(CW$code\fR to be executed after the surrounding scope has been
compiled.

This is exported by default. See Sub::Exporter on how to customize it.
.SH "PURE-PERL MODE CAVEAT"
.IX Header "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.
.PP
To explicitly request an \s-1XS \s0(or \s-1PP\s0) implementation one has two choices. Either
to import from the desired implementation explicitly:
.PP
.Vb 3
\& use B::Hooks::EndOfScope::XS
\&   or
\& use B::Hooks::EndOfScope::PP
.Ve
.PP
or by setting \f(CW$ENV{B_HOOKS_ENDOFSCOPE_IMPLEMENTATION}\fR to either \f(CW\*(C`XS\*(C'\fR or
\&\f(CW\*(C`PP\*(C'\fR.
