QUESTION
Experiment with the new catalog feature from Gradle 7, I'm trying to share a catalog via a settings plugin
Unfortunately documentation is quite short on that:
One option to share a catalog is to write a settings plugin, publish it on the Gradle plugin portal or an internal repository, and let the consumers apply the plugin on their settings file.
I initialized via gradle init for plugin developer using kotlin both as language and build script.
Then I swapped Project for Settings and added a dummy alias on producer

QUESTION
I'm trying to modify the metaclass for JSONObject in Groovy to make it behave as much as possible like a regular Groovy map. When I implement methods in the metaclass, some of them are straightforward like JSONObject.metaClass.size in the example below. JSONObject has a length() method and I'm just wiring it up to a new size() method, but some methods have special meanings. For example, to get the subscript assignment to work, I had to override propertyMissing, not putAt. It looks like a lot of the collection operations like each, collect, findAll, etc are similar.
My first question is what special methods would I need to override in this case to make each() work? My second question is how would I figure out the answer myself? Is there a reference somewhere with methods that get special treatment from the MOP? I tried looking at the groovy-core source code, but there's a lot in there and I don't know where to start.

import org.json.JSONArray
import org.json.JSONObject
JSONObject.metaClass.each={Closure c->
delegate.keys().each{ k-> c(k, delegate.get(k) ) }
}
JSONObject.metaClass.setProperty={String k, Object v->
delegate.put(k,v)
}
JSONObject.metaClass.getProperty={String k->
delegate.get(k)
}
JSONObject.metaClass.size = { -> delegate.length() }
def json = new JSONObject()
json['a'] = 999
json.b = 2.2
json['c'] = 'the letter C'
println json['a'] // Prints 999
println json['b'] // Prints 2.2
println json.c // 'the letter C'
println json.size() // Prints 3
//No signature of method: ... $__spock_feature_0_0_closure4.doCall() is applicable
json.each{ k,v -> println "$k = $v"}
