approved-p isn't kewl, it's clear. It designates the field as a predicate and could potentially help distinguish it from other fields ... approved-by, approved-for, etc.

This comment relates to the previous chapter. I wonder if Tcl could really be better than Common Lisp because of string manipulation.


"Tcl's syntactic shortcuts make code easier to read and more reliable."

Don't discount Common Lisp because the string manipulation isn't built up so nicely as Tcl. If you want a syntactic shortcut that's quicker and clearer it wouldn't be impossible to

write a macro like

(string-eval "posted by $email on $posting-date.")

That expands into

(concatenate 'string "posted by " email " on " posting-date ".")
