in reply to for vs. while question

Move your expression from third position to the first position: 
for (my @socks = $BASKET -> can_read(2); ; ) { 
  ... 
}

In the place you put it, it's executed at the bottom of the loop, not the top.

    Won't that put it outside of the loop (so it's only executed once)?

      Blimey yes. Ugh. OK, make it the conditional then: 
      for (;$BASKET and (my @socks = $BASKET -> can_read(2)) or 1); ) {  
  ...  
}

      and now it's nearly like the original non-for code.

      Probably simpler just to use the while. {grin}
