Hello @leppie ,

This language looks very interesting but I not sure if it fits my needs or not; I'm hoping you might answer this overly-large list of questions I've prepared.

1 - Performance.
I came across these benchmarks and am wondering if the results seem accurate to you?
If not, can you explain why not?

Of course, benchmarks aren't always indicative of real-world performance, so the more important question might be "how does IronScheme's performance compare to C# or other .Net languages in real programs"?

Regarding my use case, do you think IronScheme performs well enough for game logic (not the actual engine)?

2 - Environments/Sandboxing
It appears that IronScheme has environments; I am under the impression that this allows restricting which functions can be called and which variables can be accessed.

I am interested in allowing users to create mods, but I'm not interested in allowing them to execute malicious code e.g. reading or writing arbitrary files.

Do you know if I am right in thinking IronScheme's environments are useful in preventing that sort of thing?

3 - Runtime modification of code
I am interested in being able to do stuff such as run my program, modify a file containing IronScheme code, and reevaluate it without having to restart the program.
I saw there were some nice examples of this here.

It seems like quite a lot can be done, but are there any limitations I should be aware of?

4 - Debugging
I saw it mentioned that evaluated IronScheme code can be debugged:

enabling debug code generation (procedure)

Also R6RS's module system takes care of all (direct or indirect) library dependencies.

PS: If you enable debug code generation you can literally debug scheme scripts right in VS (it is not great, but not bad either).

Is there a procedure that can be called to enable this, or am I misunderstanding what was said? Do you know if this would work in VSCode?

I think that about wraps up my questions; my apologies for asking so many!
Thank you for taking the time to look at all this.
