[racket] how to use syntax-case

To Mr. Vincent:

Thanks for telling me.

Yeah, I've already checked `math/array' library.
But it says it is basically for typed racket, and I was not sure it is
suitable for game writing in order to manage the location of the objects;
so this time I decided to skip to use the library.

To Mr. Hendershott:

I try keeping to avoid "I-wanna-write-a-macro-anyway" disease; but this
time I likely catch the disease....
Especially syntax-rule() with recursion occasionally seems much easier to
write a function with recursion; so this time, the idea of macro ghost
possessed and didn't leave me....

Anyway, thanks guys!
