perl -MO=Terse[,OPTIONS] foo.pl
For compatibility with the old B::Terse, this module also adds a method named "terse" to B::OP and B::SV objects. The B::SV method is largely compatible with the old one, though authors of new software might be advised to choose a more user-friendly output format. The B::OP "terse" method, however, doesn't work well. Since B::Terse was first written, much more information in OPs has migrated to the scratchpad datastructure, but the "terse" interface doesn't have any way of getting to the correct pad. As a kludge, the new version will always use the pad for the main program, but for OPs in subroutines this will give the wrong answer or crash.
