The error message is right. You can't use [] for reading. If you call $foo[] outside of the left hand side of an assignment, it's a fatal error.

In this case, PsySH (the underlying library in Tinker) should have caught this and prevented it from closing though. This is now fixed in https://github.com/bobthecow/psysh/commit/ba7e315cf26389e8c111b6179aa814c3feb7e833 🙂

Thanks @bobthecow. Can we expect the stuff on the develop branch to be released soon? Anything I can do to help?
