I was rather thinking of something a bit more structured that would list each variable with its attributes and references broken out.
Do you have an example of such a facility in some other language?

Historically, various tools were used to examine a dump corefile, but I've not seen language-specific nor human-readable dumps before.

Aside from perl variables, all kinds of things will be on the heap for your perl process (eg: things allocated by libraries wrapped in XS interfaces).

    Yes, this is something you can do in Java. The Sun JVM hprof format (and similar formats for other JVMs) is not exactly human-readable but there are quite a number of tools capable of reading and analysing such dumps. The point is that the data is structured in a format amenable to analysis.

    I realise that libraries and XS code may be responsible but somehow I suspect that this is less likely in my case.
