Error on exit/quit

[LoadingBG]

When leaving the REPL using exit, I get an error:

Unhandled exception: Index out of bounds (IndexError)

If you're building against master, we've renamed that command to #quit https://github.com/crystal-community/icr/pull/119/files Though it's not standard with most REPLs, the idea being that with how ICR works, "magic commands" would conflict with variables or methods being defined. We also have a PR to add in #help. I guess the README needs some updating 😅

I read what was in the README.md file. Using # before the keyword seems to work. Maybe update the README.md then?

This seems to be still happening since at least crystal 1.2.1. I'm not using master; I'm using the distribution from homebrew, which is 0.9.0.

Coming from Ruby, exit is the expected command, so IMO, that one should at least not blow up.
