Side note: if `name` is autoloaded this will not return a "valid" value,
in the sense that the (autoload ...) value stored in `symbol-function`
is only usable when placed inside `name` and not elsewhere (e.g. you
can't `funcall` it, and if you store it in another symbol, calling the
function under that other symbol will probably fail).

Autoloads are somewhat hackish in this sense.
