Hi,
I have found an error when we define new phoenix expression inside boost namespace.
The following
<snip>
BOOST_PHOENIX_DEFINE_EXPRESSION( // line 19 (boost)(convert_to) , (proto::terminal<boost::phoenix::detail::target<proto::_> >) (boost::phoenix::meta_grammar) )
<snip>
It seems that the Phoenix result_of protocol and the utility result_of conflicts.
Is this a real issue?
No I don't think so. Why does this need to in the boost namespace in the first place? make it: BOOST_PHOENIX_DEFINE_EXPRESSION( // line 19 (boost)(convert)(convert_to) , (proto::terminal<boost::phoenix::detail::target<proto::_> >) (boost::phoenix::meta_grammar) ) namespace boost { using convert::convert_to; } I don't know what currently is considered best practice, but isn't it considered bad to put stuff directly in the boost namespace? If it isn't, what are the general rules of when something is considered for being resident in the boost namespace? Regards, Thomas
