perl -MO=Terse[,OPTIONS] foo.pl
This module prints the contents of the parse tree, but without as much
information as B::Debug. For comparison, "print "Hello, world.""
produced 96 lines of output from B::Debug, but only 6 from B::Terse.
This module is useful for people who are writing their own back end, or
who are learning about the Perl internals. It's not useful to the
This version of B::Terse is really just a wrapper that calls B::Concise
with the -terse option. It is provided for compatibility with old
scripts (and habits) but using B::Concise directly is now recommended
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.
