A fun contains an (indirect) pointer to the function that implements
the fun.</p>
- <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
- of <c>apply/3</c> or worse.
- 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,
- namely the <c>fun Module:Function/Arity</c> syntax.</p></warning>
-
<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>
