I wondered, whether we could add annotations and a annotations processor
to generate code/classes, that could be used to setup dsl components.
The annotations could be used for scanning for TestPlan elements on
startup, too.

When we try to get our code into modules, it might be a good idea to
have this sorted out, before (but that should not let us keep from
experimenting).
Maybe start with a global org.apache.jmeter.experimental.dsl
package/module name, and mash everything in there for a start?

Kotlin has a very similar string template format to JMeter, is there a
good way to distinguish those, or guard the JMeter ones?
It seems, that `aggregateReport` has its parameters given by a closure
(is that the right name?) , while `http` per positional parameter. Is
this a Kotlin feature, that we can mix those, or is it only a first
example and showing different ways of settings parameters on the elements?
And a completely other construction site: Currently JMeter uses a global
context, which could trip off users of the dsl, when they want to
execute plans in parallel. Would this be worse, than now?
