FOO is too generic for a label, especially in a test file full of labels and gotos. That's why I like to include bug ticket numbers in labels as a source of uniqueness. There already is a FOO: in this file; it is inside a subroutine, so there is no name clash yet, but I want to stay future proof.
Also, if this goto limitation is lifted at some point (technically it is a bug that the if block is optimized away), we don't want to start printing oops randomly, so use a null statement instead.

Do you know of a ticket number for it?
