Yes.
It might seem arguable whether requiring the programmer to numify
strings explicitly is such a burden – all it takes is a single
extra character:
skip +"3", "3";
But the problem is then: what if they forget? Consider:
skip "3";
# vs
skip +"3";
Woops.
So it’s fine to make all arguments optional (note: you don’t need
a multisub for this!), but their order MUST be fixed: if the
second parameter is there it’s always the description and if the
first is there it’s always the number of tests to skip.
So the `skip($desc)` variant must go. However, `skip()` can stay,
it doesn’t cause problems.
