Hi all,

i have a question and a problem.

The problem is that i would like to write code like:
domain=Domain([0,1]*[0,1]);
where Domain([0,1]*[0,1]) is an expression created with proto.

But of course this line of code is illegal, because i have to provide 
the type of this expression Domain([0,1]*[0,1]).
So i have to write something like this:
Domain([0,1]*[0,1])::type domain=Domain([0,1]*[0,1]);
Is this correct?

Now the question:
To avoid code like above is this what the macro BOOST_PROTO_AUTO is for?
Can i write
BOOST_PROTO_AUTO( domain,Domain([0,1]*[0,1]) ); .

Thanks in advance,
Kim Tang
