Devel::Caller - meatier versions of "caller"
use Devel::Caller qw(caller_cv);
$foo = sub { print "huzzah\n" if $foo == caller_cv(0) };
$foo->(); # prints huzzah
use Devel::Caller qw(called_with);
sub foo { print called_with(0,1); }
foo( my @foo ); # should print '@foo'
- caller_cv($level)
- "caller_cv" gives you the coderef of the
subroutine being invoked at the call frame indicated by the value of
$level
- caller_args($level)
- Returns the arguments passed into the caller at level
$level
- caller_vars( $level, $names ) =item called_with($level, $names)
- "called_with" returns a list of
references to the original arguments to the subroutine at
$level. if $names is true,
the names of the variables will be returned instead
constants are returned as
"undef" in both cases
- called_as_method($level)
- "called_as_method" returns true if the
subroutine at $level was called as a method.
All of these routines are susceptible to the same limitations as
"caller" as described in "caller"
in perlfunc
The deparsing of the optree perfomed by called_with is fairly
simple-minded and so a bit flaky.

- As a version 2.0 of Devel::Caller we no longer maintain compatibility with
versions of perl earlier than 5.8.2. Older versions continue to be
available from CPAN and backpan.
