It would be nice if both annotate and coerce had a shorter name - especially if they were compressed into a single function. Maybe something like "make?" I like how (make "foo" 'cons) reads. If you really wanted to get short, you could do something like "mk" or "to," which would work better with the annotate ordering.
I liked the "old" name (in http://www.paulgraham.com/ilc03.html) of "tag", but that appears to have gone away so the web library could use it as a name. "make" isn't bad, though.
