Nah.  

	if (!p) return (whatever);
	if (foo) {
		statement;
	} else {
		statement;
		statement;
	}
	if (!p) return (whatever);

Perfectly readable.  We have a few hundred thousand lines of code written
like this and I review all of it.  I suspect that I do more reviewing than
99% of the people on this list which makes my opinion count more because
anything that makes my tired eyes absorb the info faster is a good thing.
Same for your eyes when you get to my age.  

I also make people do

	if ((a <= B) || (c >= d)) {
		xxx
	}

even though I know, if I think about it, what the precedence is.  It doesn't
matter that I know or you know, what matters is the number of lines of code
a day you can correctly review.  Anything that helps that means that you 
are helping people make the source base better.  Try reading 30K lines of 
diffs at one sitting and tell me again that I'm wrong.  If you do, bump it
up to 60K lines :)

See, there is that age thing again.  Think V6.  And it is sort of a function,
it unravels the stack frame.
