Hi,

it is possible to define an Extension in Xtend that returns a List in List? Or one that accepts a List in List as input parameter?

Example for a normal list:

List [Object] foo(Object this) :
{this}
;

Now, how should I write the return type for the following function?

???? foo(Object this) :
{ {this}, {this} }
;

Thanks.

Hello Ruben

Xtend Collections are kind of built in and do not allow List[List[Object]] but as a workaround List[Object] should help
