<name> = defaction(<params...>){
     <declaration 0>
     <declaration 1>
     ...
     <action block (i.e. anything you would put in a rule action)>
}

For example

chooser = defaction(val){

    baz = "hello"
    qux = "bye"

    choose val {
        asdf =>
            foo(val)
        fdsa =>
            bar(val, "ok", "done")
    }
}

default parameters for function and defaction (no more configure using)

foo = function(bar = 2, baz = bar + 3){
    bar + baz
}

//-or- when it gets too long
foo = function(
    bar = 2,
    baz = bar + 3,
    qux = 4,
    quux = blah(qux),
){
   ...
}


//defaction parameters work the same way as functions

BREAKING CHANGES

You can no longer use actions as functions

//the following are now actions and cannot be used as a function
