Don't mention "tuple funs" at all
"Tuples funs" was removed a long time ago. There is no need to even mention them.

- <warning><p><em>Tuples are not fun(s)</em>.
- A "tuple fun", <c>{Module,Function}</c>, is not a fun.
- The cost for calling a "tuple fun" is similar to that

- Using "tuple funs" is <em>strongly discouraged</em>,
- as they might not be supported in a future Erlang/OTP release,
- and because there exists a superior alternative from R10B,

<p><c>apply/3</c> must look up the code for the function to execute
in a hash table. It is therefore always slower than a
direct call or a fun call.</p>
