Yes, I discovered the reason not to do this:

	if ((int i = foo ()) == 0)
		printf ("i is zero\n");
	else
		printf ("i is %d\n", i);
	
When 'if' and 'else' are separate statements, I loose the if namespace at 
the end of that statement so that the else block can't see variables 
declared within the scope of the conditional.  Fixing this would be 
tricky...
