I wanted to see how Nim compared (readability and speedwise) with what's reported here: https://jott.live/markdown/py3.11_vs_3.8
## Compile for speed with `nim c -d:danger nbody.nim`
## Run `./nbody 10000000`

Idea for making Nim's `staticExec`/`staticRead` auditable

I agree that it's impossible for Nim to protect you if you're willing to compile other people's code.

However, it could be good if Nim provided a means for auditing calls to staticExec/staticRead. Or at least provided means for someone else to write an auditing library. I imagine something like the following could work and not be onerous either to the user or the compiler:

  1. nim c --strictStatic myfile.nim

This would fail on all instances of staticExec with a message like:

ERROR: Prevented execution of myfile.nim:staticExec("/bin/echo foo") Pass --allowStatic:'myfile.nim:staticExec("/bin/echo foo")' to allow it
