> With the following code, the markup builder will recognize a call to the {{each}} method, but at runtime, it throws an error:
> {code}
> MarkupTemplateEngine engine = new MarkupTemplateEngine(new TemplateConfiguration())
>         def template = engine.createTemplate '''
>             groups.each { k, v -> li(k) }
>         '''
>         def model = [groups:[a:'Group a',b:'Group b']]
>         String rendered = template.make(model)
> {code}
> The error is:
> {noformat}
> groovy.lang.MissingMethodException: No signature of method: GeneratedMarkupTemplate0$_run_closure1.doCall() is applicable for argument types: (java.util.LinkedHashMap$Entry) values: [a=Group a]
