And what about include (it is your import) ? It allows what you want and is short ? module Mylist = struct let id x = x end module Hislist = struct let id2 x = x end module Alllist = struct include Mylist include Hislist end What is really missing is renaming when opening or doing include (with regular expression pattern matching for instance).
