\DOC do_list

\TYPE {do_list : ('a -> 'b) -> 'a list -> unit}

\SYNOPSIS
Apply imperative function to each element of a list.

\DESCRIBE
The call {do_list f [x1; ... ; xn]} evaluates in sequence the expressions 
{f x1}, ..., {f xn} in that order, discarding the results. Presumably the 
applications will have some side-effect, such as printing something to the 
terminal.

\EXAMPLE
{
  # do_list (fun x -> print_string x; print_newline()) (explode "john");;
  j
  o
  h
  n
  val it : unit = ()

  # do_list (fun x -> print_string x) (rev(explode "nikolas"));;
  salokinval it : unit = ()
}

\USES
Running imperative code parametrized by list members.

\SEEALSO
map.
