one-armed `if' when the condition is false has unspecified value.
that's not "too imperative", just "underspecified" (for some tastes).
see info node: "(r5rs) Conditionals".

furthermore, scheme doesn't (usually) have `when', so schemers should
probably take that as a hint to read the elisp docs on `when' and
compare it to their implementation's docs on `when'.

anyway, i suppose it's fair to say schemers suffer for their cause, in
one way or another (but always unportably :-)...
