Oh, sorry. Just personal preference. I don't see the point of using:
(when
single-form)
since it expands to
(if
(progn
single-form))
which seems like a waste of a progn to me. (Maybe the compiler optimizes
it away though, I don't actually know.)
In this case, I think I was just put in an anti-when mood by things of
the form:
(when a
(when b
...))
