Hi Marc, I did a search for 'semicolon' on the following page and found the interesting text below. Semicolons are used to create multidimensional lists, maybe that's what's going on in your code?
https://docs.perl6.org/language/list "Lists of Lists can also be created by combining comma and semicolon. This is also called multi-dimensional syntax, because it is most often used to index multidimensional arrays." "Unlike a comma, a hanging semicolon does not create a multidimensional list in a literal. However, be aware that this behavior changes in most argument lists, where the exact behavior depends on the function... ." "Because the semicolon doubles as a statement terminator it will end a literal list when used at the top level, instead creating a statement list. If you want to create a statement list inside parenthesis, use a sigil before the parenthesis... ." HTH, Bill. PS I would presume some variation of 'next' would work where you're using 'walkTheHash', but I don't really know for sure.
