Performance issues

Hi, in my I3 with 2GB, Clever is with a bad performance. This is the benchmark result:

1) Computes the same 100-term polynomial 100,000 times inside a single function body
ref: http://dan.corlan.net/bench.html
running tests ....
-- Clever: 9.33593
-- PHP: 3.46506
-- Python: 2.70739
-- Ruby: 11.8761
2) Benchmark test for Single Threads
running tests .....
-- Clever: 2.86844
-- Lua: 0.621246

I think is possible optimize code generation or execution to user function without user function calls like this:

import std.io;
import std.math;

function foo(x)
{
         var y = math:sqrt(x);
         var z = math:sqrt(y);
         return y + z;
}

io:println(foo(x));

I'm planing to change the Value::setObj method to do not copy the type members, instead using a lazy strategy to load the members to the instance, just performing such operation on OP_MCALL and OP_PROP_[WR] instructions. I've checked and it decreased 1sec on the polynomial test.
