I do not know how to convince B::Deparse (or B::Xref for that matter) to give you the starting line number. What do you plan to do with that information once you have it? Maybe the ideas in Re: 'extract' subs from source code can help. Perhaps if you poke around PPI you can figure out how to get the line numbers.
