Testing @ast()

This file is just for testing the \@ast() verb. It previously used a dotpath like class.ClassName.methods.MethodName but should not support an array-access path like class[ClassName].methods[MethodName].docblock[Description]. Both should work, as I do not wish to break backward compatibility.

So for the dot-path:

@ast(class.Tlf\Scrawl.methods.add_template_dir.docblock.description, ast/default, trim.fake_filter.something)

And the array-access path:

@ast(class[Tlf\Scrawl].methods[add_template_dir].docblock[description], ast/default, trim.test_fake.nothing)
