Re-implementing the whole InteractiveSession for the "packed" setup probably isn't necessary, maybe we can just inject a reduced version that only includes .CommandLineArgs?

I prefer using that over System.Environment.GetCommandLineArgs() because the latter starts with the path to fsi.dll when running under the actual dotnet fsi, and we’d have to trim it manually.
Moreover, if the code is packed as a self-contained executable, trimming is unnecessary/wrong. It'd be great if the injected fsi.CommandLineArgs could free us from the manual if-else.

Maybe it's just a matter of injecting these lines right after the first module declaration?

#if COMPILED_INTERACTIVE
module fsi =
  let CommandLineArgs = System.Environment.GetCommandLineArgs()
#endif

(By the way the snippet above is hugely confusing as it contains the path to fsi.dll... Only under an interactive FSI session...)

Yeah. I thought about something like that. I assume that fsi.CommandLineArgs is slightly different from S.E.GetcommandLineArgs(), so I would like to sit and try running under different combinations. but if you can assume me, at least that give me motivation to sitdown 😄
