75 This plugin provides a C<concise> command that uses L<B::Concise> to dump
76 optrees of expressions.
78 The code is not actually executed, which means that when used with
79 L<Deve::REPL::Plugin::OutputCache> there is no new value in C<_>.
81 The command takes the same options as L<B::Concise/compile>, e.g. C<-basic> or
82 C<-exec> to determine the dump order, C<-debug>, C<-concise> and C<-terse> to
83 determine the formatting, etc.
