Пакет mosml: Информация

Moscow ML provides a light-weight implementation of full Standard ML,
including Modules and some extensions.  Standard ML is a strict
functional language widely used in teaching and research.

Moscow ML is based on the Caml Light system, which gives fast
compilation and modest storage consumption.

   * The full SML Modules language (structures, signatures, and functors)
     is now supported, thanks to Claudio Russo.
   * Also, several extensions to the SML Modules language are provided:
      - higher-order functors: functors may be defined within structures
        and functors
      - first-class modules: structures and functors may be packed and
        then handled as Core language values, which may then be unpacked
        as structures or functors again
      - recursive modules: signatures and structures may be recursively
        defined
   * Despite that improvements, Moscow ML remains backwards compatible.
   * Value polymorphism has become friendlier: non-generalizable free
     type variables are left free, and become instantiated (once only)
     when the bound variable is used
   * Added facilities for creating and communicating with subprocesses
     (structure Unix and Signal from SML Basis Library).
   * Added facilities for efficient functional generation of HTML code
     (structure Msp); also supports the writing of ML Server Page scripts.
   * Added facilities setting and accessing `cookies' in CGI scripts
     (structure Mosmlcookie), thanks to Hans Molin, Uppsala, Sweden.
   * The Gdimage structure now produces PNG images (using Thomas
     Boutell's gd library).
