How about this alternative ("in" and "out" blocks inside function 
body):

void foo(int a)
{
	in
	{
		assert (a > 0);
	}
	out
	{
		(ret) assert(ret > 0);
	}

	// body code

	return a;
}


or for one-liners:

void foo(int a)
{
	in assert (a > 0);
	out (ret) assert(ret > 0);

	// body code

	return a;
}
