Indeed.  However, you can prepare a statement by issuing a normal
"prepare" command.  Then later you can execute this statement using
(query 'my-prepared-statement)

I re-read the docs and I agree they're worded very badly.  I'll try
and improve the bit under "query".

I did add an example to row-for-each after replying to your previous
mail.  Hopefully that'll help.

Yeah, the current paragraph is just mumbling about prepare but
not explaining anything.

"The process of preparing programs for a digital computer
 is especially attractive, not only because it can be economically
 and scientifically rewarding, but also because it can be an aesthetic
 experience much like composing poetry or music."
