In English you can use a number of different styles to add parenthetical remarks. For example:
- Juventus, as you may know, has won the most Scudetti.
- Some would say it's 29 (and technically they're right).
- Others however claim it's 31 — although they're usually die-hard Juventus supporters.
Is the dash style of parenthetical remarks also allowed by Italian grammar? I know I've casually used it from time to time and no one seemed confused by it, but that doesn't make it right.
