How are others that are updating packages dealing with deprecation warnings like ┌ Warning: broadcast will default to iterating over its arguments in the future. Wrap arguments of │ type `x::DirectedGraph{Vertex{Int64},Edge{Float64}}` with `Ref(x)` to ensure they broadcast as "scalar" elements. │ …

Yeah, I don’t love this change either but I’m hoping to be proven wrong (I strongly disliked the f.(x) notation when it was proposed for v0.5 and I was super duper wrong). How about picking your favorite unicode character that looks…scalar-ish…and doing: if VERSION <= v"0.7-" ⊙(x) = x else ⊙(x…

I like wrapping in a 1-tuple. IMO it looks better and is a bit more intuitive. (And it should be equivalent to using Ref I think…)

The only difference is that when you use @. your Ref(x) wrappers turn into Ref.(x), which is to say they stop actually working as scalarizers (the same problem applies to my suggestion above). Tuple wrappers don’t have this problem, and I’m hoping we’ll get the & syntax to explicitly scalarize even …

[image] rdeits: when you use @. your Ref(x) wrappers turn into Ref.(x) , Good to know, thanks! [image] fredrikekre: I like wrapping in a 1-tuple. [image] rdeits: Unfortunately, tuple wrappers of non-bits types still allocate on v0.6 Yeah, that’s going to prevent me from using t…

Did anyone figure out how to track the line numbers down for these errors? We just ran into this when updating Gadfly.jl: https://github.com/GiovineItalia/Compose.jl/pull/282#issuecomment-418698874

Using --depwarn=error usually works well.

Any idea why that’s happening in the first place?

Yeah, what was the rationale for this change?

Sorry, I was referring specifically to the line numbers being incorrect for these errors, which I think was not discussed in that topic.

Lots of stuff to dig up in recent broadcast changes (iterate by default), scalar struct, and `@.` and references therein.
