Can [Base.eachsplit](https://docs.julialang.org/en/v1/base/strings/#Base.eachsplit) help with allocations? Also I think similar things have been discussed previously, for example [Performance of splitting string and parsing numbers](https://discourse.julialang.org/t/performance-of-splitting-string-and-parsing-numbers/92161)

UPD: another interesting idea for `eachsplit` is [Add method `split(str, dlm, ::Val{N})` for allocation-free splitting by jakobnissen · Pull Request #43557 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/pull/43557#issuecomment-1006967727)  
" Good news: `NTuple{N}(eachsplit(str, delim))` appears to work for this with no allocation 🎉"
