Excellent, thanks for the sanity check! Issue added.

I believe I've found a test case that should be added: the current tests will allow a string like "----O____Odust" to be counted as 'glasses'.

Here's an example of a solution that works, as a result.

In my testing, this code erroneously returns a false-positive when parsing the string at index one of the list below:

test2 = ["O--#--O", "----O____Odust", "more dust"]

Please let me know if I'm missing something! 🙏
