@Datseris asked if there’s a formally citable reference with the points, examples and concepts presented by @StefanKarpinski on The Unreasonable Effectiveness of Multiple Dispatch . In the slack discussion linked above, they suggested a 3 page write-up with appropriate citations. Stefan responded th…

This thread ’s scope largely overlaps with this one :sweat_smile:, but doesn’t necessarily point to actionable output, and doesn’t purpose to many examples. Examples shared there: Julia’s native AbstractArray type hierarchy is used pretty much everywhere without much fuss . (Some do experience othe…

[image] kapple: Package interoperability examples. My favorite is printing, but a more specific example is how easy it is to provide rich displays in notebooks like Pluto.jl, IJulia.jl, and QuartoNotebookRunner.jl simply by defining show(::IO, ::MIME, ::T). The utility is demonstrated very we…

ForwardDiff.jl and nearly every other package that accepts generic Real numbers

[image] kapple: Stefan responded that this write-up should have empirical evidence in contrast with the anecdotal evidence he presented in his talk. I don’t agree with this statement, in the sense that I don’t agree that the evidence is purely anecdotal. As I mentioned in the slack discussion…

This one, including their plot recipes also working together (which is something I haven’t seen in any other language) is also in the Plots.jl paper Plots.jl – A User Extendable Plotting API for the Julia Programming Language... The Journal of Open Research Software (JORS) features pee…

Multiple dispatch is really nice when converting values between types, e.g. Serialization/Deserialization. Recently I wrote a function conform(::Type{T}, data)::T where T that attempts to convert some less-structured data into a more structured format. The basic use case is that I create 1,000 struc…

As an example of non-multiple dispatch falling short – There is a python package called S3Paths. It tries to emulate the Path class in base Python for S3. However, it does not compose with Pandas because Pandas does not interact with Path objects using the correct methods. There is an open issue on …

Reducing 6 different BLAS functions to one ( julia/stdlib/LinearAlgebra/src/blas.jl at master · JuliaLang/julia · GitHub ) for (fname, elty, cty, sty, lib) in ((:drot_, :Float64, :Float64, :Float64, libblastrampoline), (:srot_, :Float32, :Float32, :Float32, libbla…

I know this thread is asking for examples, but an earlier post of mine about composability not being novel was represented as a caveat of preaching multiple dispatch. I disagree, doing familiar things easily is actually a very good reason for preaching features, like garbage collection for managing …
