I shouldn't have choosen Num for the constructor name, it led to confusions apparently.
You can replace tha Num with anything you want, doesn't change the situation.
I mean, it's not the problematic part.

Is there any news about the fix in the lexer? When can we use it?

I would hazard a guess that the Num hyperlink points to the Num
typeclass in the Prelude rather than your Num constructor.  As for
your infix constructor, I have no idea.
