[Chicken-users] define not using define

[minh thu]

Hi,

Is it possible to register symbols in Chicken, just as a global
(define ...) would do from arbitrary code?

I'd like to be able to write (setting 'color '#f32(1 0 0 0)) and have
the same effect
than a (define color (make-parameter '#f32(1 0 0 0)) unless the color procedure
already exists.

Is it possible to define 'setting' as a procedure and not as a macro
(or am I limited to use 'setting' at the top level (I don't mean the
repl))?

The fact color is procedure is nice for me, I'd rather call (color)
than (look-up 'color).

Thanks,
thu
