Get first caller and its arguments

OlegG has asked for the wisdom of the Perl Monks concerning the following question:

Is there a way to perform subj?

sub a { b() }
sub b { c() }
sub c { my ($caller, $args) = get_first_caller_with_args }

a("test", [1,2,3]);

Want to get

$caller = \&a, $args = ["test", [1,2,3]];

Have you looked at caller? In what ways does it fail to do what you want?	[reply]

The main problem is that i can't get caller args with caller(). Am i wrong?	[reply]

In the caller docs, did you read this: Furthermore, when called from within the DB package, caller returns more detailed information: it sets the list variable @DB::args to be the arguments with which the subroutine was invoked. Also look (and/or use) Devel::Caller::Perl (which uses the "called within the DB package" technique) or Devel::Caller.	[reply]

You may find the source for Devel::StackTrace instructive. `$ perl -MDevel::StackTrace -e ' hlagh("bar"); sub hlagh { quork("baz") } sub quork { print Devel::StackTrace->new()->as_string() } ' Trace begun at -e line 1 main::quork('baz') called at -e line 1 main::hlagh('bar') called at -e line 1` [download]	[reply] [d/l]


Do you know where your variables are?
