We use it for some defuns where ELisp's arglist functionality is not
refined enough to express the intention of the programmer.
For example, the "real" arglist may be

    name args &optional docstring &rest body

but the intended arglist is

    name args [docstring] &rest body

i.e. if `docstring` is not a string it's taken as the first instruction
of `body`.
