Hum, humour is difficult for someone like me who is not fluent in 
english, and my poor Collins dictionary is falling into decay ;-)
But I got the idea and I agree, of course.
I was not advocating at all for the use of this horror called 
register_globals, just wanted to say that the number of predefined php 
vars depends on it, and that it won't hurt if we use some of their names 
as parameters.

because the param hides the name of the global excepted if ...

... you use $GLOBAL[]

I think that you mean 'func_num_args', not 'func_get_arg_count'.
This is an interesting idea and it is better than testing if ($b==null) 
because it allows to distinguish between 'no argument given' and 'null 
argument was passed'.
