If for some reason you need to exclude one or multiple services when using a tagged
595+
iterator, this can be done by using the ``exclude`` option:
596+
597+
..configuration-block::
598+
599+
..code-block::yaml
600+
601+
# config/services.yaml
602+
services:
603+
# ...
604+
605+
# This is the service we want to exclude, even if the 'app.handler' tag is attached
606+
App\Handler\Three:
607+
tags:['app.handler']
608+
609+
App\HandlerCollection:
610+
arguments:
611+
-!tagged_iterator{ tag: app.handler, exclude: ['App\Handler\Three'] }
612+
