Why doesn't Julia have the `switch-case` structure?

Why doesn’t Julia have the switch-case structure? Is it unnecessary, or is there a better solution?

I suggest Pattern Matching — MLStyle.jl Documentation

julia> @match 10 begin
           1  => "wrong!"
           2  => "wrong!"
           10 => "right!"
       end
"right!"

Thank you for introducing me to a very attractive package. :handshake: :handshake:

If you’re curious, there’s a lively discussion here: A case/switch statement for Julia · Issue #18285 · JuliaLang/julia · GitHub. TLDR it could be a macro instead of being incorporated into the base syntax, as if-statements can already undergo the optimizations switch statements do. Packages have already made such macros, Match.jl is actually referenced in that issue.
