Yes, quotes are enough.

Also CCL has parenthesis already (and it is useful), but it was designed
to change operator precedence, not release reserved words.

    (title=me and) or (title=mine)

is a syntax error because "and" is a resrved word.

I think its a matter of definition. ISO8777 says left to right binding,
which is contradictory to every other definition of AND and OR I have
ever seen. Maybe its just my programming background, but I normally
think of AND being tighter binding than OR, and if you don't like it,
use parenthesis.
