Hi Christian,

Can you have a look at the attached program.

Both items of the returned sequence of the program should do the same thing.

Both do give the same, correct result: an empty sequence, but the first item unnecessarely triggers function: “local:f1#1” , while the second item doesn’t.

This a pity since “local:f1#1” could be a time-consuming function.

Cheers,

Rob
