aimuz 7e196c04ed fmt, internal/fmtsort: refactor SortedMap to use slice of structs for map sorting This change refactors the SortedMap type in the fmtsort package from using two parallel slices for keys and values to a single slice of structs. This improves code clarity and reduces the complexity of handling map entries. Affected files and their respective functions have been updated to work with the new structure, including adjustments in fmt/print.go and text/template/exec.go to iterate over the new map representation. goos: darwin goarch: arm64 pkg: fmt cpu: Apple M2 Max │ old.txt │ new.txt │ │ sec/op │ sec/op vs base │ SprintfPadding-12 21.29n ± 5% 20.89n ± 8% ~ (p=0.393 n=10) SprintfEmpty-12
