| Subject: | [Patch] Implemented op/3 declaration for Mercury compiler |

Dear all,
This mail was originally sent from my hotmail.com account; apparently
your mail server rejects emails from this server, so I am resending
this message from my logicaltypes.com server.
Sincerely,

> Dear all,
>
> I've implemented the op/3 that has LOCAL (within the current module
> only) extent for the Mercury compiler, 0.12.1. [I consider the
> global effect of op/3 in Prolog a disadvantage. As I use op/3
> frequently, I do not wish syntax for one purpose in one module to
> spill over into syntax used for another purpose in another module]
> I've changed the following files to make this change. I've run the
> old compiler and the new compiler through the test suite -- they
> both had the same test results. I've also included in my
> downloading area a couple of programs that use the op/3
> declaration. New compiler archives for Mac and Sun, as well as
> sample programs and installation instructions are available from my
> site, http://www.logicaltypes.com, under the Latest Developments
> section, until such time you are ready to roll these changes into
> your repository.
>
> Although, in theory, this change should make the compiler slower in
> compiling programs, I have not noticed a slowdown on either Sun or
> Mac implementation.
>
> See you at the PADL/POPL.
