| 6 "//Issues to resolve: | |
| 7 "//- Boolean operators surrounded by period are recognized but the | |
| 8 "// periods are not highlighted. The only way to do that would | |
| 9 "// be separate synmatches for each possibility otherwise a more | |
| 10 "// general \.\i\+\. will highlight anything delimited by dots. | |
| 11 "//- After unary operators like "defined" can assume token type. | |
| 12 "// Should there be more of these? | |
