irb(main):006:0> a.send(:!=3D, 2)
SyntaxError: compile error
(irb):6: syntax error, unexpected tNEQ, expecting tSTRING_CONTENT or =20
tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
a.send(:!=3D, 2)
          ^
	from (irb):6
	from :0

As you see, ruby can recognize a !=3D as a tNEG(not equals).

so , I convinced a method is existed for this type of a comparison.

I have to use a workaround way, ;-<
