-----------------------------
> Discovery mechanism for customizing metaclasses with a script using

> Key: GROOVY-1721
> URL: https://issues.apache.org/jira/browse/GROOVY-1721
> Project: Groovy
> Issue Type: Sub-task
> Components: groovy-runtime
> Reporter: Guillaume Delcroix
> Assignee: Jochen Theodorou
>
> Currently, it is possible to define custom MetaClasses at load time by
> following the convention:
> groovy.runtime.metaclass.java.lang.StringMetaClass
> Creating this StringMetaClass in this specific place will use this metaclass
> in lieu of the default metaclass.
> By adding ExpandoMetaClass back in Groovy, we should provide a mechanism for
> customizing metaclasses.
> For instance, we could create an expandoMetaClassScript.groovy in the package
> groovy.runtim.metaclass.
> And in this script, we would use ExpandoMetaClasses to customize classes
> behaviour further.
