Mops

   Like {Yerk}, Mops is descended from the ex-commercial
   {object-oriented} language {Neon}.  It was developed by
   Michael Hore <[email protected]>.  Mops features an
   optimising {native}-code compiler; it is much faster than
   Yerk, but less compatible with Neon.  Mops includes extensions
   such as {multiple inheritance}.

   Version 2.3.1 includes a compiler, documentation and an
   editor.

   A {Macintosh} version is available.
