Maybe some sort of const loop would work

static for(const i = 0; i< 10; i++) // i const outside of ()
{
}

If the the last two clauses were scoped as being at the end of the loop 
then it might even be able to access const values computed during the 
last pass.

const s = 356;
char[s] buf;
char[] buf2;

static for(const i = 1; cont; i<<=1)
{
	static if(i < buf.length)
		const bool cont = true
	else
	{
		const bool cont = false
		buf2.length = i;
	}		
}

Yeah, it's contrived )and brings up a pile of issues with regards to 
scoping) but, it illustrates the point.
