Hello!

In runtime, sometimes I load classes, after apply an AST with compiler
customization.

withConfig(configuration) { ast(MyAst) }

I want to offer a way to test that classes in Spock or other test
frameworks. I was thinking in offer an static method or AST, like Grails
does:

mockWithMyAst(ClassToTest)

@MockMyAst(ClassToTest)
class MyTest extends Specification {
...

But, I don't know the best way to implement that. Changing test
classloader? Changing metaClass of target class? any way to capture
classloading in spock?.... Do you have any tip or suggestion to implement
it?

Thank you!
