    1. COThis was posted before the OP mentioned that `foo` is another macro that concatenates its arguments. The problem appearing there is that concatenation with parenthesis has some difficulties, but it's precisely _because_ arguments are being passed in the _same_ way (simple text substitution), and that they do _not_ get special processing.

    2. CO@RainerJoswig Yeah, those should be quoted. I'd started with `'(a b c d e f)`, and then edited when SO's syntax highlighting didn't like the "unmatched single quote". As to the cons cells, that's mentioned in the answer: "based on the structure of the lists (i.e., the cons cells the list is made of)", but I can make that clearer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
