134B::Terse \- Walk Perl syntax tree, printing terse info about ops

141.IX Header "DESCRIPTION"
142This version of B::Terse is really just a wrapper that calls B::Concise
143with the \fB\-terse\fR option. It is provided for compatibility with old scripts
144(and habits) but using B::Concise directly is now recommended instead.
145.PP
146For compatibility with the old B::Terse, this module also adds a
147method named \f(CW\*(C`terse\*(C'\fR to B::OP and B::SV objects. The B::SV method is
148largely compatible with the old one, though authors of new software
149might be advised to choose a more user-friendly output format. The
150B::OP \f(CW\*(C`terse\*(C'\fR method, however, doesn't work well. Since B::Terse was
151first written, much more information in OPs has migrated to the
152scratchpad datastructure, but the \f(CW\*(C`terse\*(C'\fR interface doesn't have any
153way of getting to the correct pad. As a kludge, the new version will
154always use the pad for the main program, but for OPs in subroutines
155this will give the wrong answer or crash.

158The original version of B::Terse was written by Malcolm Beattie,
