The idioms I'm thinking of are:

  (if (fboundp 'foo)
      (foo bar)
    (foo-work-around bar))

which will work for `when' too, due to macroexpansion:

  (when (fboundp 'foo)
    ...do stuff...
    (foo bar)
    ...do more stuff...)

I'd probably make it work for `and' too, so you could do:

  (and (fboundp 'foo) (foo bar))

What case do you have in mind where these aren't sufficient?
Can you give examples?

No, but let's not add both unless it's actually necessary.
