[flext] More on naming...

[Jamie Bullock]

Hi Thomas,

I'm not using any DSP stuff personally, but I see in some of the objects from the zexy library the hex naming convention is used. For example in [<~] we have:

	void setup_0x3c0x7e(void)
    {
  	lt_tilde_class = class_new(gensym("<~"), (t_newmethod)lt_tilde_new, 0,
			    sizeof(t_lt_tilde), 0, A_GIMME, 0);


etc...

This suggests to me that the setup_* idiom doesn't require a "tilde" in the function name for DSP objects.

FWIW, I find the fact that Pd requires such a coupling between the entry point to the external and the external class name a bit unsatisfactory.
