This is file README for Moscow ML 2.00 for Linux/Unix (June 2000)
- 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
- 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).
