Actually this form has the disadvantage that the byte-compiler would have to
check which functions are defnied in every branch. And snice it doesn't do
that as of now, the byte-compiler won't noticve that this form does define
`mymodule-function-in-doubt' and will hencforth issue warnings when you call
that function.
Better use:
(defalias 'mymodule-function-in-doubt
(if (fboundp 'function-in-doubt)
'function-in-doubt
(lambda (..) ...)))
which makes it trivially obvious that `mymodule-function-in-doubt' will
indeed always be defined.
