Over on the usenet newsgroup comp.math.soft-sys.maple, someone asked about using Maple's overload facility to redefine the operators such as `*`, `+`, etc.

The difficulty for the submitter is that while overload (and option overload for procedures) can provide enhanced operators for new routines, it doesn't affect routines saved in the Maple Library which already have their bindings. Overloading does not subsequently change the bindings of the operators when used in (most all) Library routines.

One way to try and get around this is to actually redefine the global operators. And since overload is on topic, one can still use it in the replacements that one writes.

In order to redefine global operators one must first unprotect them. They are protected for a very good reason. If the replacements are not adequate then Maple can fail in a multitude of ways. It's a case of caveat emptor.

What single change in Maple would you want more than any other?

Maybe it's an enhancement, or a functionality change, or a bug fix.

It looks like `forget` works on procedures with option 'cache'.

I realize that there is a routine Cache:-RemovePermanent. But should `forget` be clearing the permanent Cache entries for a procedure?

> cacheFunc := proc() option cache; print(args); args; end proc:
> Cache:-AddPermanent( cacheFunc, [5], 10 );
> op( 4, eval(cacheFunc) );
                      Cache(512, 'permanent' = [5 = 10])
 
> forget(cacheFunc);
> op( 4, eval(cacheFunc) ); # NULL return, it's empty

Here's a first working shot at an external, programmatic mechanism for opening .mw worksheets/Documents as new tabs in an already running Maple Standard GUI session.

This involves a `sh` shell script, runnable in Unix/Linux/OSX/cygwin. Maybe someone could post a MS-Windows .bat batch file equivalent.

The basic idea is this: you have a GUI session open. But you want to be able to open other .mw files in that session without having to go through the GUI's File->Open menu every time ...

Maple's Standard GUI has context-sensitive menus. Those are the menus that appear when one right-clicks on a output (or input, in a Dcoument).

Those context-menus can be customized.

Below is an example which adds a new submenu. The new submenu is populated automatically according to the types of thing found within the object itself.

It's an alternative to a menu-item that already exists, which shows up as "Help on Command". But that existing item only...
