incorrect methods yield success

Sorry, that's not really much to go on, the behavior looks correct to me. $jsonpackage->new creates a new object (in this case of type Cpanel::JSON::XS). encode is a method, but encode_json is not, but in the second call of jsonsolute, $json->$jsonefunction calls encode_json as a method, meaning that the parameters that the function encode_json sees are actually ($json, {key => 'value'}), and it doesn't know how to handle the object $json, which is of type Cpanel::JSON::XS, so it dies.

use warnings;
use strict;
use Data::Dump;

dd jsonsolute('JSON::MaybeXS', 'encode', 'decode');
dd jsonsolute();
print "Done\n";

sub jsonsolute {
    my ($jsonpackage, $jsonefunction, $jsondfunction) = @_;
    $jsonpackage ||= 'JSON::MaybeXS';
    $jsonefunction ||= 'encode_json';
    $jsondfunction ||= 'decode_json';
    dd $jsonpackage, $jsonefunction, $jsondfunction;
    if ( !defined eval "require $jsonpackage; 1" ) {
        die "package $jsonpackage missing\n";
    } else {
        my $json = $jsonpackage->new(pretty => 1, canonical => 1);
        dd $json;
        my $encoded = $json->$jsonefunction({key => 'value'});
        my $decoded = $json->$jsondfunction('{"key":"value"}');
        dd $encoded, $decoded;
        return $encoded, $decoded;
    }
}

__END__
