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