Review of Andrei's std.benchmark

[Peter Alexander]

I don't see why `benchmark` takes (almost) all of its parameters 
as template parameters. It looks quite odd, seems unnecessary, 
and (if I'm not mistaken) makes certain use cases quite difficult.

For example, suppose I want to benchmark a function several times 
with different parameters and names, how would I do that?

foreach (i; 0..10)
{
     printBenchmark!( format("Test %d", i), { someFunc(i); } )();
}

This won't work because i isn't known at compile time, and for 
some use cases it can't be known at compile time.

I wouldn't mind if there was some real benefit to taking these as 
template arguments, but there doesn't seem to be any value at all 
-- it just limits usage.
