I wanted to bring this here before actually asking it, as it seems to be one of those borderline questions that I could see as potentially being closed due to being too broad:
How many punctuation marks can you place in a row and have it still be grammatical?
This sentence is an example (which I thought, "How silly.").
The above statement uses four punctuation marks in a row at the end of the sentence.
Other exchange sites, such as Code Golf, would welcome questions like this with open arms. Would this site as well, or is it better left here on meta?
