Yes, it was spoken about, but NOBODY mentioned using -, instead of/in place of: () , : ; ! And we even covered using "...". But thanks for proving just how little you understand what courses English majors did have to take; your uneducated post proves that nobody should talk about things they don't know about nor understand at all.
