I just tried it, and I'm not convinced. The main problem is that you'll 
end up with:

do {
	switch(b) {
	case c:
		if (x)
			break;
		else if (y)
			continue;
while(a);

Where the break statement will affect the switch() and the continue 
statement will affect the do-while() loop which is kinda confusing.

Especially if you're so far down in the function body that the 
do-while() and switch() statements aren't visible any more.
