72 | =head1 DESCRIPTION |
73 | |
74 | This plugin provides a C<concise> command that uses L<B::Concise> to dump |
75 | optrees of expressions. |
76 | |
77 | The code is not actually executed, which means that when used with |
78 | L<Deve::REPL::Plugin::OutputCache> there is . |
79 | |
80 | The command takes the same options as L<B::Concise/compile>, e.g. C<-basic> or |
81 | C<-exec> to determine the dump order, C<-debug>, C<-concise> and C<-terse> to |
82 | determine the formatting, etc. |
