+-- IMPORTANT: When using the @fun@ anti quoter, one must be aware that
+-- the function pointer which is automatically generated is freed when
+-- the code contained in the block containing the anti quoter exits.
+-- Thus, if you need the function pointer to be longer-lived, you must
+-- allocate it and free it manually using 'freeHaskellFunPtr'.
+-- We provide utilities to easily
+-- allocate them (see 'Language.C.Inline.mkFunPtr').
