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.
