Do you remember what the reasoning was? I would think that since we
accept #t=,10 , it would logically make sense to also accept #t=10,
and #t=10 is just the short form for the latter. But maybe we had a
good reason to reject it?

In any case, the specification was using both and either we need to
remove the example or fix the production rule.
