This is normal.

  let f ... = ...
  
  let g ... = ...

The function g can use f but f cannot call g because g is not known at
that point.  If f must also call g, then f and g are mutually
recursive and you should declare them as

  let rec f ... = ...
  
  and g ... = ...

You can also group your functions as methods of an object (these can
call each other) :

object(self)
  method f ... = ... self#g ...
  method g ... = ... self#f ...
end
