I want to test for a key being defined in one hash, and if it is, then it should be a hash, and I need the value of that second key. So I was testing my syntax with raku and got the following: raku Welcome to ๐๐๐ค๐ฎ๐๐จโข v2020.12. Implementing the ๐๐๐ค๐ฎโข programming language v6.d. Built on MoarVM version 2020.12.

Exactly the same line, executed twice, produces two significantly different answers. I think this shouldn't happen.Thread Next
