Print the contents of a list, with `first` preceeding the first item (default: `"["`), `last` following the last item (default: `"]"`) and `sep` separating items (default: `"; "`). A printing function must be provided to print the items in the list. The `flush` parameter (default: `false`) should be set to `true` for the outer-most printing call. Setting inner calls to `true` - for example, for nested values - prevent indentation from working properly.

Example: `pp ~flush:true Format.pp_print_int Format.std_formatter [1; 2; 3]`
