casts issues

[dmitry....@gmail.com]

Hi All,

1. [casts_downgrade] - uses [nt2::groups] while [as_group] typedef uses [tag::group_] instead of [tag::groups_]. Is this by design? If is, we need to include <nt2/include/functions/group.hpp> header.

2. The same with [nt2::toints] and [nt2::touints]

3. I have problem with nt2 compilation on Visual Studio 2013 while processing <nt2/table.hpp>

------

1>.. \nt2\build\include\nt2\operator\functions\container\casts.hpp(138): error C2953: 'nt2::ext::casts_intfloat<Expr,From,To,boost::enable_if_c<boost::dispatch::meta::is_integral<To>::value&&boost::dispatch::meta::is_unsigned<To>::value,void>::type>' : class template has already been defined

1> .. \nt2\build\include\nt2\operator\functions\container\casts.hpp(122) : see declaration of 'nt2::ext::casts_intfloat<Expr,From,To,boost::enable_if_c<boost::dispatch::meta::is_integral<To>::value&&boost::dispatch::meta::is_unsigned<To>::value,void>::type>'

------

As far I research this - this depends on order of <cast.hpp> - <casts.hpp> includes - the latter include fail.

Hi,

It's indeed a bug, casts was just copy-pasted from cast and slightly
adapted.

Fixed in ff9f3938a6cb7c05a8dc29660b0ae4ec6417a53d.

Thanks for the report.
