Custom tags support is a very important feature imo that currently lacks to the yaml component.
It is basically allowing things like:
services:
square_printer:
arguments: [ !color red ]By having a dedicated system for tags, we could centralize their management and avoid duplication (here and here).
If wanted, it could also be used in the core to remove reserved keys in config files.
For example,
services:
_defaults:
autowire: true
my_service:
class: FooBar
arguments:
- '@service1'
- =iterator:
- '@service2'
- '@service3'
# could become
services:
!defaults:
autowire: true
my_service:
class: FooBar
arguments:
- '@service1'
- !iterator
- '@service2'
- '@service3'WDYT?
