You're saying that you actually do that in cases where x may be an empty
string, and that it's useful to get a True result in at least one such case?
If you are saying that, it needs more details; but if you're not saying
that, it's not a relevant use case.

Sure -- that's what .find() is for, after all. But you're also saying that
your algorithms expect to search for empty strings? Like in:
index = option_letter_string.find(letter)
if index >= 0:
you make sure that list_of_option_functions is suitable for processing
both the first option in option_letter_string and an empty "option letter"?
