I've just upgraded to build 1532 and this very slight deficiency of VAX is still present...so, here goes:
When I use the Boost.Optional template class (see http://www.boost.org/libs/optional/doc/optional.html), VAX does not present me with the appropriate member suggestions when using -> to access the encapsulated type.
Now, Boost.Optional uses a pointer like syntax to represent the concept of an optional value, so in some ways it's like a smart pointer type - and VAX can handle smart pointers (boost::shared_ptr, at least!).
Here's an example:
#include <boost/optional.hpp>
struct TimeStamp
{
u32 seconds;
u32 microseconds;
};
typedef boost::optional<TimeStamp> OptTimeStamp;
OptTimeStamp ot1;
ot1->?
Pressing Ctrl+Space here yields no suggestions, but I would expect to see 'seconds' and 'microseconds'.
Now, I've had a look at the Boost.Optional code...and it's reasonably straight forward, but something's acting as a barrier between VAX and the appropriate type declaration - it might be the use of Boost template metaprogramming facilities, specifically boost::mpl::if_ that gets in the way?
Anyway - I suppose this is a nice to have :-) |

template support in VA is getting better, but as you have just discovered it still has its limitations. thank you for the clear example, i was able to reproduce the problem quite easily here.

Lack of suggestions with tricky C++ template type
