As with `methodMissing` it is best practice to dynamically register new properties at runtime to improve the overall lookup
performance.
-[NOTE]
-`methodMissing` and `propertyMissing` methods that deal with static methods and properties can be added via
-the <<core-metaprogramming.adoc#metaprogramming_emc,ExpandoMetaClass>>.

+Static variant of `methodMissing` method can be added via the <<core-metaprogramming.adoc#metaprogramming_emc,ExpandoMetaClass>>

=== GroovyInterceptable
The gapi:groovy.lang.GroovyInterceptable[] interface is marker interface that extends `GroovyObject` and is used to notify the Groovy runtime that all methods should be intercepted through the method dispatcher mechanism of the Groovy runtime.
