Double right arrowhead?

[Ivan Panchenko]

But the fast forward symbol is not what I am talking about. It should
be just two simple strokes for an arrowhead (I have noticed this
symbolism quite often, recently), twice, not two black triangles. The
succeeds symbol is a relation symbol that is used if an object a
succeeds an object b (a ≻ b), so this does not fit, either. (That
said, is the use of the greater-than sign actually inappropriate here?
Semantically ambiguous characters such as the ASCII apostrophe are a
thing, after all.)
