WARNING: deprecated syntax "_ as an rvalue"

question

#1

I am trying Julia v0.6 and this warning is new. It doesn’t have a line number attached to it, so I don’t know where I have to look in the source.

I know that the identifier _ will be used to discard values in the future like in Haskell (if I am not confusing the languages). Why the warning?


#2

Because the warning is telling you that you are reading from it.
