Kia ora!

Yes, this is the crux of it but I avoided gathering from mce_loop_f in this way 


%hash2 = mce_loop_f {
    MCE->gather(split ' ', $$_);
} $data_file;

Because (and I can be totally wrong in assuming so) gather will only return %hash2 in this instance while I am also interested in returning $counter2. The docs show gather can be called multiple times, doing so will complicate teasing apart the returned output from mce_loop_f{}. It would be great if gather can behave a bit like a sub so WYSIWYG 
#hypothetical code:
#alas if gather can gather two or more data types
(%hash2, $counter2) = mce_loop_f {
    my $internal_counter2++;
    MCE->gather(split '\s', $$_, $internal_counter2); #return data typ
+es
} $DATA_F;
