  # SupplyTimeWindow
  
  ```
  use SupplyTimeWindow;
  
  my $s = Supplier.new;
  my $t = $s.Supply.time-window: 1;
  
  start react whenever $t { .say }
                                  
  for ^10 -> $i { $s.emit: $i; sleep .5.rand }
  
  ```
  
  SupplyTimeWindow creates `time-window()` new method on `Supply`ies that receives the size of the time window in seconds.
  Every time the original `Supply` emits, it will emit an `Array` with each value emitted less than `time window`'s size seconds.
  
  ```
  multi method time-window($seconds --> Supply) {...}
  
  ```
  
  It also accepts a optional named parameter `transform`, it's a `Callable` that will be used to transform the time window array.
  
  ```
  multi method time-window($seconds, :&transform! --> Supply) {...}
  
  ```
