I don't think the meaning of this operator is obvious. Right now, the only operators whose meaning are not immediately obvious (in my eyes) are: @ - error suppression & - make reference in some cases, bitwise and in others ^ - bitwise xor but what are you gonna do :) For an operation as complicated as "use the first variable that exists" I would be most comfortable with: $d = first-existing: $a, $b, $c; This way, no conflict with functions (parse error in previous php versions), and it is extremely clear. The parser would look for T_FIRSTEXISTING ':' existing_varlist in the expression section, and of course defining existing_varlist as: existing_varlist: variable | existing_varlist ',' variable ; Greg
