Why would having the standard library present make what you want to implement slower? "High level wrappers" are not necessarily any slower. There's nothing preventing you from making your own high-performance primitives without ditching Julia's standard library. There are tons of examples out there of user-defined types in Julia code that are just as efficient as the built-in ones: - https://github.com/JeffBezanson/FixedPointNumbers.jl - https://github.com/JuliaGraphics/ColorTypes.jl - https://github.com/JuliaDiff/DualNumbers.jl - https://github.com/dpsanders/ValidatedNumerics.jl For a simple, self-contained example, see examples/modint.jl <https://github.com/JuliaLang/julia/blob/master/examples/modint.jl>.
