Access to the raw input

[Arch-vile]

To my understanding there is no access to the original raw input text? I had a use case where I had the need to pick some values out of the lines and produce output with those fields and the raw input

As a simple example transform
timestamp debug 100ms john <rest of the line>
to
100 john timestamp debug 100ms john <rest of the line>
where the 100ms and the username where picked from the line and then printed with the original line.

Could be as simple as just having access to field _raw that would contain the original input.

Just realised that one can do this
agrind '* | * as raw'
to achieve that. I think automatic access to the _raw would be good feature anyway.
