List of things we may change once we drop support for old julias

Just to have a place to note down things that come to mind to be eventually worked on after #4200 is resolved.

• Replace Pidfile.jl by FileWatching.Pidfile in GAP.jl, Polymake.jl, Singular.jl (needs julia 1.9):
  • Replace Pidfile.jl dep by stdlib GAP.jl#1207
  • Replace Pidfile.jl dep by stdlib Singular.jl#871
  • Replace Pidfile.jl dep by FileWatching stdlib Polymake.jl#523
• Clean up package extensions in AbstractAlgebra.jl, Hecke.jl
• Use Base.pkgversion to determine one's own version, instead of the current variation of Toml parsing hacks. See Add pkgversion(m::Module) to get the version of the package that loaded a given module JuliaLang/julia#45607:
  • AbstractAlgebra
  • Use Base.pkgversion to query Nemo version Nemocas/Nemo.jl#2127
  • Use Base.pkgversion to query the Hecke version thofma/Hecke.jl#1933
  • Polymake
  • Use Base.pkgversion to query the Singular.jl version Singular.jl#874
  • Drop unnecessary dependency on Compat GAP.jl#1217
  • Oscar
• Reminder: things to do if we switch to requiring Julia >= 1.10 GAP.jl#1118

@everyone please just edit this and add things to the list instead of writing comments with suggestions.

There are PRs for everything in this list, so I see no reason to keep it any longer
