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)
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 the perlfunc manpage
The deparsing of the optree perfomed by called_with is fairly simple-minded and so a bit flaky.
