Another method that manipulate optional arguments Joo ChurlSoo 09 Mar 2020 11:35 UTC

There is not only classical music in this world.
There are also folk, pop, and hiphop music.
And people play and listen to the right music according to time, place and situation.

The fox (srfi 54 and 183) is just another format procedure that makes use of
another method that manipulate so-called optional arguments.
The method can not be comprehensive, not extensible, and not wonderful, but it
and its output are simple, easy, and convenient to use, under some circumstances.
And I think all is not right that is comprehensive, extensible, and wonderful.
