Yes, this makes more sense and removes a step.
The problem is: I think I was unclear stating what the loop is supposed
I need to find *more than one* string fragment per string.
Say I need to verify the existence of the sequences "joe", "bill" and
"leon" in a string - but the next time I may need only find "joe" and
"bill", which is why I went with the 0, 1 scheme.
It may be better stated as: "How do I find arbitrary numbers of
substrings in arbitrary order in a string pythonically?"
