You are not using a hash of symbolic references
in A.pm. You are using a reference to a hash of code
references.

Still assuming hash references, do you mean:

$MOD::A::b->{oranges}();
$MOD::A::b->{open}("pairs");

$antwort doesn't need to be a global variable, but $antwort_text_1 .. 5 do,
as symbolic references don't

See if this gets you going. It's one possible answer.

Does this run for you?
Perhaps you could suggest a better solution.
Perhaps. I know you're building some sort of hash tree, but I have no
idea why. Can you tell us what you're aiming for?

Greetings,
Im trying to generate a tree of nested hashes [of an

Perhaps you could suggest a better solution.
Currently I'm trying to use symbolic references
according to the literature
but without much luck.

I wanted to eliminate the duplicated code so I wrote:
sub list {
my $self=shift;
my $key=uc(shift);
print "using '_$key' as hash name\n";
return sort keys %${"_$key"};
}
which according to the section of symbolic referenc

I can call a method on an object using the following:
$objref->func()
However, if I try to call this using a symbolic reference:
my $func_name = "$objref->func";
&{$func_name)();
then I get the following error:
"Undefined subroutine &main::$objref->func called.."
The problem is that the perl
