Hello monks,

With B::Concise, it's possible to get a syntax tree for specific subroutines, CODE refs, or the top "main" program. However, what I need is the syntax tree (or trees) for an entire module. I.e., I need some kind of dump of Perl's parse of a module, which might include "dead" code that is never called. I would also want to recursively do the same thing for any other modules/sources pulled in with use or require (I'd probably ignore core modules and a few others, but haven't decided yet).

This will be part of a sort of static analysis tool I'm working on. This therefore imposes the constraint that the target module is essentially unknown code, and should be considered 'read-only' in the sense that I can't require the developer to add instrumentation to the code itself.

Also, requiring a recompile of perl is not an option since this code will be widely distributed. So, unfortunately all perl -D flags are a no-go.

One rather ugly hack I explored briefly was to try to extract all sub names and use/require modules from the source and run B::Concise on each result, but, beyond the fact it's a terrible idea, there's no way that I know of to run B::Concise on anon subs without their compiled CODE ref handy, which I wouldn't, and couldn't, in general, compile. (Whenever sub { ... } shows up in the code, the entire sub just shows up as a single anoncode line.)

Is there a way to do what I'm describing? Efficiency is not high on my list of priorities.
