Another approach might be to add STRING_EQUAL and STRING_MATCHES (or similarly unambiguous names) operators that do not do the variable lookup.
The documentation would start with: if(<string> STRING_EQUAL <string>) if(<string> STRING_MATCHES <regex>) ...i.e., not mentioning <variable> anywhere for these operators.
