> I noticed some strange behavior when closures inside a builder throw exceptions:
> {code}
> import groovy.transform.TypeChecked
> @TypeChecked
> class TestBuilder extends BuilderSupport {
>   Object createNode(Object name, Map map){
>     println "Create node $name: $map"
>     new Node(null, name, map)
>   }
>   Object createNode(Object name){
>     println "Create node $name"
>     new Node(null, name)
>   }
>   Object createNode(Object name, Object value){
>     println "Create node $name, value $value"
>     new Node(null, name, value)
>   }
>   Object createNode(Object name, Map map, Object value){
>     println "Create node $name: $map, value $value"
>     new Node(null, name, map, value)
>   }
>   void setParent(Object parent, Object child){
>     println "set parent of $child to $parent"
>     ((Node)parent).append( (Node) child)
>   }
> }
> def builder = new TestBuilder()
> // First case
> // expected: MissingMethodException tring to call String.foo()
> // actual: MissingMethodException tring to call b(Closure)
> try {
>   builder.a {
>     b {
>       error('xy'.foo())
>     }
>   }
> }catch (e){
>   assert e instanceof MissingMethodException
>   assert e.method == "foo"
> }
> // Second case
> // expected: one call to buidler.createNode('b')
> // actual: two calls to buidler.createNode('b')
> builder.with {
>   a {
>     b {
>       error("xy".foo())
>     }
>   }
> }
> {code}
