I tried to use a code reference, but that failed as well. One difference I had to use is that I can't call object->new() outside of the closure as the new calls _init which is what I need to have run in a thread. I can change the object so new just creates a new object and then call _init in the closure if that would help.

sub getFDCObjects
{
    my $self = shift;
    my %fdcObjectHash;
    my @threadQueue;
    my %switches = $self->getSwitches();
    for my $switch (keys %switches)
    {
        #my $fdcObject = $self->_openFDCObject($switches{$switch}, $sw
+itch);
        my $swObject = $switches{$switch};
        my $threaddo = sub {
                my $self = shift;
                my $swObject = shift;
                my $switch = shift;
                my $fdcObject = FosDataCapture->new($log, $swObject);
                return ($fdcObject, $switch);
        };

        my $thread = threads->create($threaddo,$swObject, $switch);
