This is a very common pattern in the functionnal
programming.
It's a good usage in OCaml to give the maximum of safety
in the code,
and expose only what is necessary.
The solution given by Chingfan gives one function, with
the followin
pattern :
> let function1 arg1 =
> let function2 arg2 arg3 = …
> in function2 arg1 []
so in this case, the function2 is localy defined inside
function1, and
only function1 is visible from outside.
This allow to control how the data will be processed, and
to be sure to
get well-formatted arguments.

oke,
So if I understand it right then with let function2 arg2 arg3 = …
you say I have a function named function2 with two arguments and
with the in you say that one of the arguments is a empty list.
