the reason i said that bit is html and xml (i know they're not human languages and they're certainly not in the area i'm asking about) but they make heavy use of opening and closing - their structure is based on it - and i wondering is there any language that uses of more than one glyph for an open or close, like in xml and html? they have a group of characters that together mean open or close, like <title> and </title>. i can't think of anywhere that happens in english.
again, minus mistakes, so it might make sense:
