NAME DESCRIPTIONCurrent experiments Accepted features Removed features SEE ALSO AUTHORS COPYRIGHT LICENSE NAME perlexperiment - A listing of experimental features in Perl DESCRIPTION This document lists the current and past experimental features in the perl core. Although all of these are documented with their appropriate topics, this succinct listing gives you an overview and basic facts about their status. So far we've merely tried to find and list the experimental features and infer thei

redo LABEL redo EXPR redo The redo command restarts the loop block without evaluating the conditional again. The continue block, if any, is not executed.

NAME DESCRIPTION NAME Memoize::Storable - store Memoized data in Storable database DESCRIPTION See Memoize.

msgsnd ID,MSG,FLAGS Calls the System V IPC function msgsnd to send the message MSG to the message queue ID. MSG must begin with the native long integer message type, be followed by the length of the actual message, and then finally the message itself. This kind of packing can be achieved with pack("l! a*", $type, $message) . Returns true if successful, false on error. See also the IPC::SysV and IPC::SysV::Msg documentation. Portability issues: msgsnd in perlport.

NAME SYNOPSIS DESCRIPTION SEE ALSO COPYRIGHT AND DISCLAIMERS AUTHOR NAME Pod::Perldoc::ToPod - let Perldoc render Pod as ... Pod! SYNOPSIS perldoc -opod Some::Modulename (That's currently the same as the following:) perldoc -u Some::Modulename DESCRIPTION This is a "plug-in" class that allows Perldoc to display Pod source as itself! Pretty Zen, huh? Currently this class works by just filtering out the non-Pod stuff from a given input file. SEE ALSO Pod::Perldoc COPYRIGHT AND DISCLAIMERS Cop
