Is there a good way of determining if GraalPy is in an interactive prompt/REPL?

[da-woods]

In CPython, looking at sys.ps1 seems fairly reliable (the attribute doesn't exist if it isn't interactive). In GraalPy it seems the attribute always exists.

If not, this isn't a significant blocker to anything.

I don't see any good way currently. But we can change our ps1 initialization to match CPython's if that helps you.

Thanks for the answer - I don't think it's too important so probably isn't worth the change. (i.e. I'm not even sure if we're going to use the feature I was trying to implement this for, and it still works without, just maybe a bit slower)
