@ would be inside string literal so should cause little confusion from
D's side, but for example would force one to escape '@' in email
addresses (more rare).

If we're talking about writing other languages inside D, then "@" would be in conflict with Objective-C which uses that for all new syntax (that isn't available in plain C).
