[Maxima-discuss] Methods with "@@": examples and screenshots

[Eduardo O. <edu...@gm...>]

Hi list,

This e-mail is a better version of this one:
  https://sourceforge.net/p/maxima/mailman/message/59187622/

I always had the impression that defstruct was just the core of
something, and users were expected to write the rest... here is my
most recent attempt to write that "rest".

The core of my code is just this,

  "@@4"(structname,o,method,Args) :=
     apply(concat(structname,"__",method), append([o],Args));

  "@@" (o,method) :=
     buildq([o,method], lambda([[Args]], "@@4"(op(o),o,method,Args)));

  infix("@@",200,201);

and the code, with examples and screenshots, is here:
