Why do you need a *list* of the operators? For that, a quick grep returns
this in lib/irb/ruby-lex.rb of your ruby distro:

472:    @OP.def_rules("+=", "-=", "*=", "**=", 
473: 		  "&=", "|=", "^=", "<<=", ">>=", "||=", "&&=") do


If you're actually looking for it in parse.y, I don't think it would appear
as those operators. For instance:

6428:       case '+':
....
6438:         if (c == '=') {
6439:            set_yylval_id('+');
6440:            lex_state = EXPR_BEG;
6441:            return tOP_ASGN;
6442:         }


Cheers,
