I often wonder why all Schemes don't have something like Gambit-C SIX syntax. After all, the the traditional syntax would still be available, if one needs or prefer it. One needs the traditional syntax to do things like genetic programming, neural networks or macros. One may often prefer it. There are people who cannot swallow Lisp prefix syntax.  I have shown Lisp, PLT and Bigloo to many people who uses tools like Mathlab. I always succeed in making them accetp Lisp. Here is what I do:

1 --- If the person needs a lot of math and computer algebra, I compile Maxima on SBCL to make it very fast. In fact, it becomes as fast as Lisp itself. People are amazed at the possibility of doing the same thing that they were doing in Matlab, and using similar syntax.

2 --- If the person works with network, Internet etc. I try to sell them Scheme. I discovered that it is much easier to sell them Bigloo and Gambit, that have an infix syntax than PLT or Larceny.

Since providing an infix syntax seems to be very easy,  I wonder why this does not become official. As far as infix syntax goes, I have a few complaints to file against the existing ones. 

1 --- SIX requires one to declare types. People with a Matlab background finds it annoying.

2 --- Maxima adds a lot of annotations to the prefix representation of the infix syntax. I am not sure, but I believe that this may slow processing.

3 --- Bigloo requires the presence of the bigloorc file at every point where one launches the interpreter. If the programmer forgets the bigloorc file, goodbie infix syntax.

I am sure that all the above problems can be easily fixed.

I am about to teach this in PLT for the first time. I'll point to lecture notes when I have them. -- Matthias
