`parse_text`

parse_text is about 76 lines long
Its job is to take apart a POD paragraph like this:

      Be aware that the optimizer might have optimized call frames
      away before C<caller> had a chance to get the information.
      That means that C<caller(N)> might not return information
      about the call frame you expect it do, for C<< N > 1 >>.  In
      particular, C<@DB::args> might have information from the
      previous time C<caller> was called.

Locate the escaped sections like C<caller> and C<< N > 1 >>
