call_traits

Hi!

I have noticed that the call_traits<>::const_reference translates to 
const& even for 'small built-in types' I was wondering if it wouldn't 
be "better" i.e more efficient to let it translate to const by-value 
for these types instead?
The only reason I can think of Not to do this, is to make a const_cast
work, but as I understand the standard doesn't require a const_cast 
to succeed at all?
Perhaps this could be made optionable in the config?
