N3 uses "!" (after UUCP) and the design note http://www.w3.org/DesignIssues/N3Alternatives#Syntax where it is noted that N3 might acquire expression syntax so reserving + - * / makes sense. * and + are already used in property paths. To add expressions in patterns to SPARQL, it would take some kind of expression marker like `` or ?(?x+?y) (c.f. shell syntax). To me "!" suggests "not". "/" builds on file paths and paths in HTTP URIs. Andy
