Re: the break and return limitation

For the return statement, it's because otherwise it may be ambiguous:

	...
	return
	f(1,2,3)
	...

Is this a return with no values or a tail call to f?

The restriction on the break statement is a leftover from an experimental
break-with-labels. "break f(x)" coud be "break f" followed by "(x)".
