you can do sow about global vars (by iterating for example over the symbol table of a package
and tie each variable to package like Monitor.pm (advanced perl prog) when you do sow you can have control each time
one of the vars access(read/write) about lexical i think theres away to getting them you can look at pmtools
i hope im not confuse you here. but if you can get them then you can monitor them the same way

Subject: [Israel.pm] Knowing what variables were modified in a -d: debugger?
I'm writing a -d: debugger, and it's very important for me to know what
variables changed in every line (I want to keep their content [in
Data::Dumper format] only when they change, otherwise it's a waste of
HDD space, and will cause other [internal, of the system I use] problems
Is there a good way to know what variables changed in each line?
Unlike "watch" in the Perl debugger, I also need to "know" if
arrays/hashes/references were modified.
And I don't want to run regular expressions over the lines to match a
I hope there's some B::* module for that.
An answer such as "it cannot be done" is also alright, in case you are
100% positive of it.
