NAME
Devel::Caller - meatier versions of "caller"
SYNOPSIS
use Devel::Caller qw(caller_cv);
$foo = sub { print "huzzah\n" if $foo == caller_cv(0) };
$foo->(); # prints huzzah
use Devel::Caller qw(called_with);
sub foo { print called_with(0,1); }
foo( my @foo ); # should print '@foo'
DESCRIPTION
caller_cv($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.
BUGS
All of these routines are susceptible to the same limitations as
"caller" as described in "caller" in perlfunc
The deparsing of the optree performed 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.
