Which is equivalent to: 

	if (A)	{
	    X;
	    if (B) 	{
	    	Y;
	    }
	} else	{
	    Z;
	}
	
n'est pas?
I find the last easier to read (if not A, skip B altogether, rather than
putting B at the same `level' as its predicate).  Can you provide an
example that is significantly `clearer' (whatever meaningful term you
prefer ;-) with an 'andif' than with nesting in the block? 
 (N.B., this is not just another `but we
  don't really NEED that' argument; I found
  the 'andif' obfuscatory.  Consider:
 
  	if (A)
		X
 	andif (B)
		Y
	andif (C)	/* if A && !B or if A && B ? */
		etc
 )

Well, you don't *really* make code portable by defining it to be so ;-)
(no, responses to my foolishness are not necessary)
