Native code function name

[better2being]

Hello~ I have a small question,
that is built-in function .toString() will get
function func_name() { [native code] } .
but native function in stpyv8 won't get its name, like Ln16 in stpyv8/examples/global.py:
print(ctxt.eval("hello.toString()")) # function () { [native code] }
So I wonder if it can be change. Thanks.
