Trying to define a method != doesn't wfm, even with define_method:

irb(main):013:0> class Object; define_method(:!=) {|arg| self != arg }; end
class Object; define_method(:!=) {|arg| self != arg }; end

SyntaxError: compile error
(irb):13: parse error, unexpected tNEQ, expecting tSTRING_CONTENT or
tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
class Object; define_method(:!=) {|arg| self != arg }; end
