I think Julia is advancing very great, not too slow and not too fast. I imagine that people can wait for some more time for the language to stabilize. Julia is a genuine scientific computing language, not just an extension for doing scientific programming on top of a general-purpose language. As suc…

[image] nalimilan: more dignity Since when was programming dignified???

The goal was not to protect against uninitialized data via the length of the name, but just by forcing you to be explicit. I do find uninitialized very long though; I would be fine with simply renaming it to uninit.

Which kind of initialization we have to wait after deprecation phase? Edit: [image] nalimilan: I like the new syntax, but uninitialized is indeed a bit long and hard to type. We could probably find something shorter but with more dignity than junk. Maybe raw? unfilled? blank? And BTW could…

[image] jeff.bezanson: I do find uninitialized very long though; I would be fine with simply renaming it to uninit :+1: I guess it won’t be optional, so could there be other values to pass here, like a valid default value &/or the original uninit / junk / inseclogindeets (lol). A default wou…

I’d also really like to see a convenience constructor for constructing an arbitraily initialized array complementing ones, zeros, etc. I’d really like a naive empty(T, dims...) from a users perspective. But I guess I can also live with uninit(T, dims...) given the fact that there is an empty functi…

[image] Liso: And BTW could you explain what exactly do you like? What will be more simple or more clear? Why not to keep default Array constructor to use uninitialized memory? See Array{T}(initialization,...) syntax - #2 by mbauman .

[image] carstenbauer: I’d really like a naive empty(T, dims…) from a users perspective You would need to use e.g. OffsetArray{T}(uninitialized, dims...) for any AbstractArray other than Arrays. Creating a bunch of Array specific functions when there are so many other type of AbstractArrays s…

[image] kristoffer.carlsson: You would need to use e.g. OffsetArray{T}(uninitialized, dims…) for any AbstractArray other than Arrays. Not if the T @liso meant was the array type, not the element type, i.e.: empty(OffsetArray{String}, dims...)

FWIW, empty is completely different from what we’re discussing here: it creates a collection with zero elements. So another name would be needed (uninitialized, uninit, etc.). Anyway uninitialized(Array{Int}, dims...) is almost identical to Array{Int}(uninitialized, dims...), so the main question i…

[image] y4lu: A default would probably be handy for arrays of Union types, and could even be performant if done lazily? ie set or return the default value on read if still undefined / unwritten, like a hidden(?) union of type x + initialized boolean that will fall back to type x on true (initial…
