I'm eager to hear what other and you will say.
Now since blocks are closures, and I remember that long time ago I
implemented simply
infinite stream with a closure in CLOS it should be a same in Pharo.
Now it was probably 20 years ago so I forgot the exact implementation.

I hope that you have fun with our neat language.
