There are now three different before attributes for when which are evaluated in this very order:

• beforeOptions
• beforeInput
• beforeAgent

The documentation tries to describe this "highlander principle" but it would be much more logical and readable if there was only a single attribute before allowing only a single value of options, input or agent.
E.g.:

    when {
        before git 
        // ...
    }

Migration consideration: The old dedicated before attributes should not be removed right away. Instead those attributes should be marked deprecated and their usage should yield warnings in the log.
